Abstract:

A working method of a process cartridge, and the process cartridge and an imaging device. The process cartridge comprises a developing frame (21), a drum frame (31), a developing roller (22), and a photosensitive drum (4). The developing frame (21) can rotate relative to the drum frame (31). The developing roller (22) moves between an imaging position and a cleaning position relative to the photosensitive drum (4). The photosensitive drum (4) comprises a drum tube (41) and a first driving assembly (42) mounted at an axial end of the drum tube (41). The developing roller (22) comprises a roller body (221) and a second driving assembly (5) mounted at an axial end of the roller body (221). The first driving assembly (42) and the second driving assembly (5) are located on the same side of the process cartridge. The working method of the process cartridge comprises an imaging step and a cleaning step. In the imaging step, the developing roller (22) is in contact with the photosensitive drum (4), the first driving assembly (42) drives the photosensitive drum (4) to rotate, and the second driving assembly (5) drives the developing roller (22) to rotate. In the cleaning step, the developing roller (22) is separated from the photosensitive drum (4), the first driving assembly (42) drives the photosensitive drum (4) to rotate, and the second driving assembly (5) drives the developing roller (22) to rotate.
