Abstract

The present invention relates to a system for making discriminations between cartridges for housing toners to be equipped on image forming apparatus such as electrostatic copiers, laser beam printers, facsimiles, etc. in which while a cartridge indicating means is provided on a part of a toner housing cartridge, an indication detecting means for detecting the aforementioned cartridge indicating means is provided on the image forming apparatus proper side, so that the suitability of the type or position of the cartridge inserted is detected by detecting the cartridge indicating means by the aforementioned detecting means, when the cartridge has been inserted into the cartridge inserting part of the image forming apparatus proper.

Claims

1. A developer housing cartridge equipped with a hollow container for housing a developer and a cartridge indicating means for indicating the type or position of the cartridge, which is installed on an outer surface of the hollow container and wherein said cartridge indicating means is a small separate container housing toner and/or carrier of a same type as that of the developer housed in the cartridge.
