Movable member and image forming apparatus

A movable unit attachable to an apparatus main assembly of an image forming apparatus, movable to the apparatus main assembly, and to which a cartridge is detachably mountable, the cartridge including a toner accommodating container for accommodating toner and a cover member provided at an end portion of the toner accommodating container with respect to a longitudinal direction of the toner accommodating container, the movable unit comprising:

• a frame;
• a rotatable photosensitive drum provided in the frame;
• a charging wire provided in the frame, extending along a rotational axis direction of the photosensitive drum, and configured to electrically charge a surface of the photosensitive drum;
• a cleaning member provided in the frame, movable between a first position and a second position with respect to a direction of the rotational axis direction, and configured to clean the charging wire by contacting the charging wire;
• and
• a mounting portion provided in the frame and to which the cartridge is mountable so that the longitudinal direction is the rotational axis direction,
• wherein the cleaning member includes a base portion and a plurality of projected portions projected upward from the base portion when the movable unit is in an attitude in which the movable unit is mounted to the apparatus main assembly,
• wherein in a state in which the cartridge is mounted to the mounting portion, the cleaning member is positioned in the first position and movement of the cleaning member from the first position to the second position is restricted by the cartridge,
• wherein the plurality of projected portions includes a first projected portion projected most upward from the base portion among the plurality of projected portions and entirety of the first projected portion is disposed in a region of the base portion on a side of the first position with respect to a center position of the base portion in the rotational axis direction, and
• wherein in a state in which the cartridge is mounted to the mounting portion, the first projected portion is provided in a position in which the first projected portion overlaps with the toner accommodating container as viewed in the rotational axis direction and in which the first projected portion overlaps with the cover member as viewed in a direction perpendicular to the rotational axis direction.
