Image forming apparatus.
The switching mechanism has a connector in which the filter and the duct are connected in a first direction, The connecting body is slidable in the first direction. The image forming apparatus according to claim 1.
The aforementioned switching mechanism is A biasing member that biases the connector toward the first side in the first direction, such that the filter is positioned downstream of the fan, A connecting member is provided to connect the door that opens and closes the container and the connecting body, and when the opposite side of the first side in the first direction is designated as the second side in the first direction, the connecting body slides to the second side in the first direction in conjunction with the closing of the door, thereby positioning the duct downstream of the fan. The image forming apparatus according to claim 2.
A door for opening and closing the aforementioned container, A door sensor that detects that the door is in the closed position and outputs a first signal, An input unit that receives an input for initiating the ozone liquid creation mode and outputs a second signal, A display unit that displays information, The system includes a control unit that, when the second signal is input from the input unit and the first signal is not input from the door sensor, displays information on the display unit prompting the closing of the door. The image forming apparatus according to claim 1.
The image forming unit includes a first photoreceptor on which a first yellow toner image is formed, a second photoreceptor on which a second magenta toner image is formed, a third photoreceptor on which a third cyan toner image is formed, a fourth photoreceptor on which a fourth black toner image is formed, and an intermediate transfer belt on which the first to fourth toner images are transferred. When the control unit receives the second signal from the input unit and the first signal from the door sensor, it separates the first to third photoreceptors from the intermediate transfer belt, charges the first to third photoreceptors, and generates ozone. The image forming apparatus according to claim 4.

Description

Embodiments of the present invention relate to an image forming apparatus. The image forming apparatus has an image forming unit that forms a toner image on a charged photoreceptor. There is a need to provide an image forming apparatus with diverse functions. Japanese Patent Publication No. 2011-99892 A perspective view of the image forming apparatus according to the embodiment.A schematic diagram of the main body of the image forming apparatus.Hardware configuration diagram of an image forming apparatus.Perspective view of the image forming unit and the ozone processing unit.Perspective view of the area surrounding the ozone treatment unit.Diagram illustrating the operation of the switching mechanism.Perspective view of the container.A perspective view of the back of the door.Perspective view of the locking mechanism.Diagram illustrating the operation of the locking mechanism.Perspective view of the door sensor.Flowchart for preparing ozone solution.The first example of the control panel display.A second example of the control panel display.Third example of the control panel display. The image forming apparatus of the embodiment will be described below with reference to the drawings. Figure 1 is a perspective view of an image forming apparatus M according to an embodiment. For example, the image forming apparatus M is located in a workplace such as an office. The image forming apparatus M comprises an image forming apparatus body 1 and an ozone processing unit 20. In this application, the Z, X, and Y directions of the Cartesian coordinate system are defined as follows: The Z direction is the vertical direction, and the +Z direction is upward. The X and Y directions are horizontal. The X direction is the left-right direction of the image forming apparatus body 1. The Y direction is the front-to-back direction of the image forming apparatus body 1, and the +Y direction is forward. Figure 2 is a schematic diagram of the main body of the image forming apparatus 1. The main body of the image forming apparatus 1 performs the process of forming an image on a sheet S. The sheet S may be paper. The main body of the image forming apparatus 1 includes a scanner unit 2, an image forming unit 3, a sheet supply unit 4, a transport unit 5, an inversion unit 9, a tray 7, a control panel 8, and a control unit 6. The scanner unit 2 reads the image information of the object to be copied as brightness and darkness and generates an image signal. The scanner unit 2 outputs the generated image signal to the image forming unit 3. The image forming unit 3 forms a toner image based on an image signal from the scanner unit 2 or an external source. The toner image is an image formed from toner or other materials. The image forming unit 3 transfers the toner image onto the surface of the sheet S. The image forming unit 3 heats and pressurizes the toner image on the surface of the sheet S to fix the toner image to the sheet S. The sheet supply unit 4 supplies sheets S one by one to the transport unit 5 in accordance with the timing at which the image forming unit 3 forms the toner image. The sheet supply unit 4 includes a sheet storage unit 10 and a pickup roller 11. The sheet storage section 10 stores sheets S of a predetermined size and type. The pickup roller 11 removes the sheets S one by one from the sheet storage section 10. The pickup roller 11 supplies the removed sheets S to the conveying section 5. The transport unit 5 transports the sheet S supplied from the sheet supply unit 4 to the image forming unit 3. The transport unit 5 has a transport roller 12 and a registration roller 13.
