DEVELOPING BOX, PROCESSING BOX, AND IMAGE FORMING DEVICE

WIPO Patent Application WO/2018/028480

A1

A developing box (32), a processing box (3), and an image forming device (1). The processing box (3) comprises the developing box (32) and a photosensitive drum box (31). A supported member (352) is disposed on the developing box (32). A supporting portion (345) is disposed on the photosensitive drum box (31). When the processing box (3) is mounted in the image forming device (1), the supported member (352) and the supporting portion (345) receives a pressure (F) applied by a pressure application component (72) in the image forming device (1), and an included angle (α) between the direction of the pressure (F) and the normal direction of a contact portion between the supported member (352) and the supporting portion (345) is not smaller than a friction angle between the supported member (352) and the supporting portion (345), and in this way, the processing box (3) can be forcibly pushed by using a simple forcibly-pushing mechanism, and an excessively great force applied on a local part of the processing box (3) is avoided.
