ABSTRACT:
In a removable process kit for a copying apparatus having a device such as a developing device and/or cleaning device which includes a magentic field generator such as magnet roll, the process kit is designed so that the magnetic field generator can be removed from the process kit. Thus, the magnetic field generator can be used with the main body of the copying apparatus for a long period of time independently of the durability of the process kit. The heavy magnetic field generator need not be provided in the process kit itself and this leads to light weight and reduced cost of the kit.
