Abstract
An image forming apparatus includes an image bearing member, an optical sensor including a light emitting portion, a light receiving portion and a cover member, a cleaning member, and a supporting member movable between a proximity position where the optical sensor opposes the image bearing member with a predetermined distance and a spaced position where the optical sensor is spaced from the image bearing member by a distance more than the predetermined distance to form a cleaning space between the optical sensor and the image bearing member. When the supporting member is in the proximity position, the cleaning member is in a retracted position retracted from an opposing space between the optical sensor and the image bearing member. When the supporting member is in the spaced position, the cleaning member is in a cleaning position for cleaning the cover member with the cleaning member.
