Toner cartridge

A toner hopper which is arranged upwards of the developing unit is elevatably supported in the image forming device in the vertical direction thereof and the connection between the toner hopper and the developing unit can be cancelled by lifting up the toner hopper when drawing out the developing unit so that the structure of the connection portion therebetween can be simplified and the sliding portion can be eliminated to thereby eliminate wearing at the connection therebetween. Furthermore, an apparatus for automatically raising and lowering the toner hopper and an apparatus for maintaining the horizontality of the toner hopper when being elevated and lowered is provided.

Developer unit and a toner hopper for an image forming device

A toner cartridge unit for a copying machine having a double shutter at the mouth of the toner cartridge. The double shutter is locked when the cartridge is not attached to a toner hopper of the copying machine and prevents toner from coming out. Owing to the double shutter structure, the outside of the cartridge is always clean. When the cartridge unit is attached to the hopper, many locking and releasing mechanisms for the double shutter and a third shutter provided at the hopper entrance work sequentially and automatically as the cartridge is moved from a preparation site to a supplying site of the toner hopper.
