MECHANISM AND METHOD FOR MOUNTING AND REMOVING A TONER CARTRIDGE OF A DEVELOPMENT DEVICE

摘要

A mechanism for mounting and removing a toner cartridge in a development device for use in an electrophotographic recording apparatus, a photocopier, and the like comprises a rotating member (21) for mounting a cartridge (24) filled with toner for replenishment, onto a main body (20) at a set position and opening an opening (11, 17a, 18a). A cross-shaped projection (23) on the main body and a cross-shaped groove (26) on the cartridge are provided for preventing lifting of the cartridge (24) when the rotating member (21) is rotated in one direction. In the method of mounting and removal, the rotating member (21) is rotated from the set position to the other direction, and is subsequently returned to the set position to have the projection (23) and the groove (26) engaged or disengaged.
