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 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.

Claim (Index 24):
An image forming apparatus comprising:\n a main assembly; a drum cartridge including a photosensitive drum and capable of being exchanged by being mounted in and dismounted from said main assembly; an optical print head including a light emitting element configured to emit light to which said photosensitive drum is exposed and including a lens array configured to focus the light onto said photosensitive drum, said optical print head being movable between an exposure position where said photosensitive drum is exposed to the light by causing said light emitting element to emit the light in a state in which said optical print head is positioned to said drum cartridge and a recording paper retracted from said photosensitive drum than the exposure position is; and a bar-like cleaning member configured to clean a light emergent surface of said lens array, wherein said cleaning member includes, a grip portion provided on one end side of said cleaning member with respect to a longitudinal direction of said cleaning member and configured to be gripped, a slidable portion provided on the other end side of said cleaning member with respect to the longitudinal direction of said cleaning member and configured clean the light emergent surface by sliding on the light emergent surface, and a contact portion configured to contact a portion-to-be-contacted fixed to said main assembly as a separate member from said optical print head and said drum cartridge so that said slidable portion inserted from an outside of said main assembly toward between said photosensitive drum and the light emergent surface and cleaning the light emergent surface by sliding on the light emergent surface is prevented from further moving toward a downstream side with respect to an inserting direction thereof.
