PURPOSE:To uniformize the temperature rising conditions of a developer support cylindrical body which receives heat from a latent image body and to eliminate irregularity in the density of development by arranging a heat generating body at a prescribed position on the opposite side of the developer support cylindrical body from the latent image carrier. CONSTITUTION:The heat generating body 7 which serves as a blade as a developer control member is heated by an AC power source 8. This heat generating body 7 is on the opposite side of the sleeve 2 which is the developer support cylindrical body from a photosensitive drum 1 and arranged so that the center angle to the prolongation 21 extending from the nearest position of the sleeve 2 to the photosensitive body 1 and running in the center 20 of the sleeve 2 is within a range between + or -45 deg.C. |
