Abstract
A tandem system for the formation of color images having a plurality of image carriers integrated into a single cartridge and developing devices designed to be detachable from or attachable thereto, thereby improving the integrity of maintenance and cutting back on running costs. At least two image formation stations are provided, each having an image carrier, a charger, a developing device and a primary transfer roller disposed therearound. A transfer medium is passed through the image formation stations to form color images in a tandem fashion. A plurality of image carriers are disposed with respect to an image carrier cartridge, which is detachable from and attachable to the system proper while they are mutually positioned. A developing device is provided with respect to each image carrier attached to the image carrier cartridge in a detachable/attachable manner.
