Description

Waste powder recovery container and image forming device Technical Field The invention relates to the field of electronic imaging equipment, in particular to a waste powder recovery container and an image forming device. Background An image forming apparatus forms an image on a recording material using an electrophotographic image forming process. The image forming apparatus includes a developing device, a waste toner recovery container, and a toner container. The image forming apparatus visualizes an electrostatic latent image formed on a photosensitive drum using a powder developer supplied from a toner container, and performs a fixing process after transferring the visualized image onto a recording medium directly or through an intermediate transfer body. The waste powder remaining on the surface of the photosensitive drum is removed by the cleaning device, discharged to the outside of the cleaning device by the screw conveyor, and stored in the waste powder recovery container. The existing waste powder recovery container has the problem that the waste powder recovery container is loosened in the image forming device due to improper arrangement of the structural positions with the positioning function and the clamping function, and waste powder cannot be stably conveyed into the waste powder recovery container, so that the waste powder is leaked, and poor image is caused. Furthermore, in order to effectively utilize the internal space of the image forming apparatus and thereby achieve the purpose of reducing the overall volume of the product, the existing waste powder recycling container and the toner container are assembled together. However, since the toner container is generally a long cylinder, if the positioning structure for clamping the waste toner recovery container and the toner container is not configured in good balance during the printing process, the gravity center of the toner container may shift, and the toner in the toner container cannot be smoothly supplied into the developing device, thereby causing leakage or blockage of the toner and seriously affecting the printing quality.
