Abstract
An image forming apparatus includes a drum cartridge including a photosensitive drum, a movable optical print head including a light emitting element and a lens array, and a portion-to-be-contacted. The photosensitive drum and a light emergent surface of the lens array are spaced from each other to permit insertion of a cleaning member therebetween from outside of the main assembly. The portion-to-be-contacted is provided in the main assembly and configured to be contacted by the cleaning member to prevent further insertion of the cleaning member after the cleaning member cleans the light emergent surface by sliding on the light emergent surface from one end side toward the other end side of the light emergent surface with respect to a longitudinal direction of the lens array.
