Claims

[Scope of utility model registration request]

A plurality of developer supply means each having a developer supply roller and removably disposed on the side of the electrostatic latent image carrier; a developing section that selectively receives a supply of developer through the developer and supplies the same to the surface of the electrostatic latent image carrier; and a locking mechanism that irremovably locks at least the developer supplying means that the developing section faces. A developing device comprising:
