Abstract
A process cartridge includes a charging wire for charging a photosensitive member and a cleaning member for cleaning the charging wire. When the cleaning member moves from a first position to a second position while sliding on the charging wire, a moving member in a third position is moved to a fourth position. However, the moving member remains in the fourth position when the cleaning member moves from the second position to the first position.
Claims19
A process cartridge comprising:
- a frame;
- a photosensitive member disposed inside the frame and having a surface;
- a charging wire extending in the frame, the charging wire configured to charge the surface of the photosensitive member;
- a cleaning member configured to clean the charging wire and that is movable in a moving region between a first position and a second position while sliding on the charging wire;
- and
- a moving member that is movable between a third position and a fourth position, wherein a movement of the cleaning member from the first position to the second position moves the moving member in the third position to the fourth position, and the moving member remains in the fourth position when the cleaning member moves from the second position to the first position.
