像装置。 It has an endless developing belt made of a flexible non-magnetic material as a developer carrier that conveys developer to the surface of the latent image carrier, and is inscribed in this developer belt to support rotation of the developer belt. A developing device is provided with a plurality of internal rollers and a magnet disposed opposite to the latent image carrier at the inner position of the belt. At least two of the inscribed rollers are spaced apart from each other in the circumferential direction of the latent image carrier to set a trajectory, and the distance from the surface of the latent image carrier can be increased or decreased. . A developing device characterized in that each of these inner rollers is connected to a driving means for increasing and decreasing the separation interval independently or integrally.
