PURPOSE:To simplify toner feeding by aligning sides of plural developing devices opposed to a photosensitive body at the time of arranging plural stage developing devices storing developers having different colors oppositely to an image carrier and projecting the opposite sides gradually in the descending order. CONSTITUTION:A transparent original platen consisting of glass is set on the upper face of an outside device 1 and an original 0 is set so that its image side to be copied is turned downward and covered with an original pressing plate 3. A moving optical system 10 including a short focus array 11, an original illuminating lamp 12, etc., is arranged in the device 1 correspondingly to the original platen 2 and a rotary belt type electrophotographic sensitive body 4 is arranged under the device 10. In said constitution, developing devices 15-18 storing yellow, Magenta, syane and black toners are fitted to one outside of the photosensitive body, and at that time the faces contacted with the photosensitive body 4 are aligned and opposite faces are gradually projected in the descending order and toner feeding ports are formed on the projected side. Consequently, toner can be supplied without drawing respective developing device.
