ABSTRACT:
An image forming apparatus for forming an image on a recording material, to which apparatus a process cartridge is detachably mountable, wherein said process cartridge includes a photosensitive drum unit and a developing unit, wherein said photosensitive drum unit includes a photosensitive drum, and said developing unit is rotatably engageable with said photosensitive drum unit and includes a developing roller for developing an electrostatic latent image formed on said photosensitive drum, and wherein said developing unit is movable between a contact position in which said developing roller is in contact to said photosensitive drum and a spaced position in which said developing roller is spaced from said photosensitive drum, said image forming apparatus including means for exposing said photosensitive drum with light through a transmission member to form the electrostatic latent image, wherein said exposure means is positioned below said process cartridge when said process cartridge is mounted to a main assembly of the apparatus; moving means for moving said developing unit to the contact position or to the spaced position; and a cleaning member for cleaning said transmission member in interrelation with an operation of said moving means.
