像用スリーブ。In order to create a visible image by adsorbing the developer to the image forming part of the photoreceptor, a developing sleeve that has a magnet inside and knurling on the surface to transfer the developer is placed facing the photoreceptor. The developing sleeve has a surface whose axial length is longer than the image forming area of the photoreceptor and shorter than the inside of the photoreceptor, and a small diameter circumferential portion is provided at both ends of the developing sleeve.
