ABSTRACT:
A camshell type photoelectric color image printer includes a photoreceptor for holding a latent image on its surface, a charger for charging the surface of the photoreceptor, a laser writer for forming a latent image on the charged surface of the photoreceptor, plural developers for developing the latent image with color toners, a transfer drum for holding a recording sheet on which the developed latent image is transferred, a cleaner for cleaning residual toner on the photoreceptor, and a cartridge which holds the photoreceptor, the developers, the cleaner and the transfer unit. The developers are located under the photoreceptor, and the cartridge is removable from the color image printer. An upper part of the color image printer is movable relative to the main body of the printer. The transfer drum is located at an upper position of the photoreceptor in the printer, so that a recording sheet can be easily removed from the printer when the recording sheet is jammed in a circumferential portion of the transfer drum.
