Abstract

PURPOSE:To obtain an excellent picture with no development of fringes by dividing a developing roller into a driving roller part and developing roller part. CONSTITUTION:Developing roller 15 is divided into developing roller part 14 and driving roller part 13 which is harder and greater in diameter than the developing roller part. Driving roller part 13 is driven by the drum to rotate without any slide and developing roller part 14 can be brought into contact with the drum surface by adequate pressure. So that no developer will stick to driving roller part 13, removal blade 16 is provided. Thus, an excellent picture with no development of fringes can be obtained.
