Abstract

An image forming apparatus employing a face-down delivery system in which the plane of the recording medium at any position relative to any other position assumed by the recording medium beginning with a stacking tray and ending with a delivery tray does not exceed 90.degree.. The apparatus includes a detachable cartridge which includes a photosensitive member, a charging device and a cleaning device. In one preferred embodiment, register rollers and fixing rollers are positioned relative to each other such that a substantially zero angular deviation exists in the path traveled by the recording medium between these two pairs of rollers.
