Description

Conveying device Technical Field The present invention relates to a conveying device. Background In the related art, in an image forming apparatus including a fixing portion, condensation may occur in a guide portion of a conveying path because a recording medium immediately after fixing is in a high temperature state. For example, patent document 1 discloses a structure in which a heat insulating sheet is attached to an upper structure of a conveyance path, and a PET film is supported by the heat insulating sheet in a cantilever manner. In this structure, occurrence of dew condensation is suppressed by the heat insulating sheet, and frictional resistance of the recording medium is reduced by the PET film. Prior art literature Patent document 1 Japanese patent laid-open No. 2007-91382 Disclosure of Invention However, in the structure described in patent document 1, there is a possibility that the recording medium is electrostatically adsorbed to the PET film. Therefore, the electrostatic adsorption may increase the conveyance resistance of the recording medium, and further may cause defects such as jamming and wrinkling of the recording medium. The purpose of the present invention is to provide a conveyance device capable of suppressing occurrence of defects due to electrostatic adsorption of a recording medium while suppressing occurrence of condensation in a conveyance path section. In order to achieve at least one of the above objects, a conveying apparatus according to an aspect of the present invention includes: a conveyance path section that conveys the recording medium on which the image is fixed by the fixing section; a guide plate provided in the conveyance path section and guiding conveyance of the recording medium; a heat insulating material mounted to the guide plate, and An electroconductive resin sheet provided so as to sandwich the heat insulating material between the electroconductive resin sheet and the guide plate, The resin sheet is grounded. According to the present invention, it is possible to suppress occurrence of defects due to electrostatic adsorption of the recording medium while suppressing occurrence of dew condensation in the conveyance path portion.

Detailed Description Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. Fig. 1 is a diagram schematically showing the overall configuration of an image forming apparatus 1 according to an embodiment of the present invention. Fig. 2 is a diagram showing a main part of a control system of the image forming apparatus 1. As shown in fig. 1, an image forming apparatus 1 is a color image forming apparatus of an intermediate transfer system using an electrophotographic process technique. That is, the image forming apparatus 1 forms an image by primary-transferring the toner images of the colors Y (yellow), M (magenta), C (cyan), and K (black) formed on the photosensitive drum 413 onto the intermediate transfer belt 421, and then secondary-transferring the toner images of the colors 4 onto the sheets S (recording medium) fed from the paper feed tray units 51a to 51C after the toner images of the colors 4 are superimposed on the intermediate transfer belt 421. In the image forming apparatus 1, a tandem system is adopted in which photosensitive drums 413 corresponding to the 4 colors YMCK are arranged in tandem in the traveling direction of the intermediate transfer belt 421, and toner images of the respective colors are sequentially transferred to the intermediate transfer belt 421 in one process. As shown in fig. 2, the image forming apparatus 1 includes an image reading section 10, an operation display section 20, an image processing section 30, an image forming section 40, a sheet conveying section 50, a fixing section 60, and a control section 101.
