Abstract:
1. An electrophotographic image forming apparatus for forming an image on a recording material in the state that a cartridge is detachably mounted to a main assembly of said electrophotographic image forming apparatus, said electrophotographic image forming apparatus comprising: a cartridge supporting member movable between an inside position in said main assembly of the apparatus and an outside position which is outside said main assembly of the apparatus and in which the cartridge is mountable and the mountable, in the state that the cartridge is detachably mounted thereon; a light source for emitting light; a light guide member, provided on said cartridge supporting member, for guiding the light emitted from said light source along a longitudinal direction of an electrophotographic photosensitive drum to electrically discharge charge remaining on said electrophotographic photosensitive drum after a developed image formed on said electrophotographic photosensitive drum is transferred onto the recording material in the state that the cartridge is in an image forming position, which is the inside position, for forming the image on the recording material; an interrelating member for moving said light source to an operating position where the light emitted from said light source enters said light guide member in interrelation with movement of said cartridge supporting member from the outside position to the inside position; and a positioning member for positioning said light source at the operating position relative to said light guide member provided on said cartridge supporting member positioned in the inside position.
