Image forming apparatus and drawer member

An image forming apparatus for forming an image on a recording material, the apparatus comprising:

• a main assembly provided with an opening;
• a drawer member movable relative to the main assembly while supporting an image forming portion including at least an image bearing member for carrying a toner image, between an inside position which is inside the main assembly and in which an image forming operation is enabled and an outside position to which the drawer member is drawn out of the main assembly through the opening and in which a cartridge including at least a part of the image forming portion is mountable to and dismountable from the drawer member;
• an optical unit provided in the main assembly and configured to emit light onto the image bearing member and including a light emission opening and a transparent member covering the light emission opening;
• a cleaning member provided in the main assembly and configured to clean a surface of the transparent member by moving relative to the optical unit;
• and
• an operating portion configured to move the cleaning member in a process of movement of the drawer member from the inside position to the outside position or a process of movement of the drawer member from the outside position to the inside position,
• wherein a direction of the movement is perpendicular to a longitudinal direction of the image bearing member.

A drawer member usable with a main assembly of an image forming apparatus, the main assembly including an opening, an optical unit configured to emit light onto an image bearing member for carrying a toner image and including a light emission opening and a transparent member covering the light emission opening, and a cleaning member provided in the main assembly and configured to clean a surface of the transparent member by moving relative to the optical unit,

• wherein a drawer member is movable relative to the main assembly while supporting an image forming portion including at least an image bearing member, between an inside position which is inside the main assembly and in which an image forming operation is enabled and an outside position to which the drawer member is drawn out of the main assembly through the opening and in which a cartridge including at least a part of the image forming portion is mountable to and dismountable from the drawer member, the drawer member comprising:
• an engaging portion engageable with a portion-to-be-engaged provided on a side of the cleaning member,
• wherein the engaging portion moves the cleaning member in a process of movement of the drawer member from the inside position to the outside position or in a process of movement of the drawer member from the outside position to the inside position, wherein a direction of the movement is perpendicular to a longitudinal direction of the image bearing member.
