DEVELOPING APPARATUS HAVING ROTATING FUSING ROLLER

摘要

PURPOSE: A developing apparatus having a rotating fusing roller is provided to smoothly flow a developer between the fusing roller and a developing roller in the case that the developer has a high density. CONSTITUTION: A photoconductive body(51) forms an electrostatic latent image by a static device and an exposing device. A developing roller(63) supplies a developer(68) to the photoconductive body for developing the electrostatic latent image. A fusing roller(67) contacts with the developing roller for depositing the developer. A metering device(61) applies pressure or electric power to maintain the developer of a surface of the developing roller at an appropriate density. A first cleaning device(69) cleans ink particles attached to the surface of the fusing roller. A second cleaning device(65) cleans the developer remaining on the surface of the developing roller after the photoconductive body develops the electrostatic latent image.
