摘要： An image forming apparatus includes a cover pivotable on a body to close an opening at a closed position and open the opening at an open position, first and second replacement units having photosensitive drums, an optical print head pivotable in one direction, a spring, and a stopper. The spring applies, to the optical print head, a force for allowing the optical print head to pivot toward the one direction so that a movement of the optical print head with a pivotal movement of the cover from the open position to the closed position is prevented from being inhibited by the first developing cartridge. The optical print head, having the force applied the optical print head by the spring, so that movement of the optical print head with pivotal movement of the cover from the open to the closed position is prevented from being inhibited by the second developing cartridge.

摘要： 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 an outside of the main assembly. The portion-to-be-contacted provided in a main assembly and configured to be contacted by the cleaning member to prevent further insertion of said cleaning member after said cleaning member cleans said 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 said lens array.
