ABSTRACT:
A developing device includes a developing section provided with an applicator for applying a developer to a latent electrostatic image and a supporting section for supporting the developing section turnably between an operating position at which the developer held on the applicator acts on image-bearing member and a non-operating position at which the developer held on the applicator does not substantially act on the image-bearing member. According to a first aspect, positioning device acts on the developing section and holds it at the operating position. According to a second aspect, there is provided device for holding the developing section at the non-operating position at the time of mounting a main body of the developing device on an image-forming machine. According to a third aspect, when the main body of the developing device is mounted on the image-forming machine, electrical connecters provided thereon are electrically coupled to each other. According to a fourth aspect, a toner cartridge loaded detachably into the main body of the developing device, not necessarily of the above type, cannot be detached from the main body of the developing device unless its discharge opening is closed with a cover member.
