The present invention relates to an electrophotographic apparatus, in which an optical writing head is disposed in the neighborhood of a photosensitive body on the inner side thereof. The photosensitive body is located in a cartridge, which can be freely inserted and drawn out with respect to the main body of the apparatus and a guiding member is disposed in the cartridge, which member guides one end portion of the optical writing head, the other end portion of which is held by the main body of the apparatus to effect the positioning of the optical writing head. By constructing it in this way it is possible to effect the exchange operation of the cartridge, in which the photosensitive body is located, without dismounting the optical writing head and no position adjusting work therefor is necessary.
