Abstract

PURPOSE: To obtain a high-quality picture for a long time with a simple constitution, by arranging a cleaner, which consists of materials having an energy value larger than surface free energy of constitution materials of the rotating material, on the outside circumference of the rotating material.
CONSTITUTION: Cleaner 24 is constituted with materials having the surface free energy value larger than that of materials constituting the circumference face, at least, of developing roller 19. Consequently, toner particles interposed between developing roller 19 and cleaner 24 are easier to transfer to the cleaner side 24 than the circumference face of roller 19. Though toner particles are stuck to the surface of developing roller 19 after developing roller 19 performs development many times, the toner stuck to the roller surface is transferred to the cleaner 24 side, which is easy to wet for the developer, due to the frictional action of cleaner 24 and their surface free energy difference. As a result, a vivid and high-quality picture without fog can be obtained for a long time.
