ABSTRACT:
An electrophotographic printer comprises an access cover for opening and closing an upper opening of a cavity in an enclosure, a rotatable head holder supported at one adjacent to the inner surface of the access cover, an optical print head provided on the inner surface of the head holder, and a process cartridge containing a photosensitive drum provided so that it can be inserted and removed through the upper opening. The optical print head may have holes provided at both ends thereof, and the process cartridge may have pins which are engageable with the holes on the optical print head, thereby to facilitate alignment between the optical print head and the photosensitive drum. The optical print head may have a surface electrode, and the enclosure may have a pressure-contact type connector, so that when the head holder is closed, the surface electrode of the optical print head and the pressure-contact type connector of the enclosure are connected to enable supply of electric power and print signals to the optical print head.
