ABSTRACT:
A color image forming device in which an operator with no special trained experience can easily replace photosensitive bodies one by one without inviting deterioration in print quality due to shear in printing. The color image forming device has photosensitive bodies having rotational shafts parallelized nearly, the photosensitive bodies being driven respectively and rotatably in a box. The color image forming device forms a color image on a transfer paper sheet by transferring sequentially color manifest images developed on the photosensitive bodies on the transfer paper sheets. The color image forming device includes a positioning and fixing implement coupled axially and removably to the front end of the rotational shaft of each of the photosensitive bodies, for positioning and fixing to the box while the end of the rotational shaft is supported rotatably; and a coupling for coupling axially and detachably the rotational shaft on the base side of the photosensitive body with a drive system fixed on the box. The color image forming device is applicable to printers of electro-photographic mode, electrostatic recording mode, or the like.
