Multi-color electrophotographic printer.

摘要

A multi-color electrophotographic apparatus is provided which includes a casing having an access cover (36A), an image transfer belt unit (37) for transferring a multi-colored image formed thereon a recording sheet, and an image-forming assembly (55) having a plurality of image-forming units. Each image-forming unit includes a photoconductor (46) and a developer (63) storing therein toner of a single different color for forming a different color toner image on each photoconductor (46). The image-forming assembly (55) is arranged to be movable between operative and inoperative positions. The operative position is such that each image-forming unit lies at an image-forming station with the photoconductor (46) thereof in engagement with an image transfer belt (38) of the image transfer belt (37) unit to transfer the toner image formed thereon in registration with one another to the image transfer belt for forming the multi-colored image. The inoperative position is such that all the photoconductors of the image-forming assembly are out of engagement with the image transfer belt for allowing an apparatus operator to unload the image transfer belt unit from the casing through the access cover (36A) without damaging each photoconductor due to rubbing with the image transfer belt.
