PURPOSE:To obtain good copies without white spots by bringing a projecting part into contact with a belt-shaped photosensitive body interruptedly to oscillate the photosensitive body and removing unnecessary carrier and coarse toner from the photosensitive body. CONSTITUTION:If the carrier and the coarse toner stuck to the photosensitive body at the development time are stuck as they are, gaps are generated between the photosensitive body and a transfer material at the transfer time, and therefore, images in these space parts are not transferred to generate white spot phenomena. A rugged oscillating plate 10 is provided in the stage of rotation of the photosensitive body 1 from the development process to the transfer process, and a developer is removed by this plate 10. That is, the photosensitive body is oscillated by the rugged oscillating plate 10 to scrape the carrier and coarse toner, thereby preventing the occurrence of white spot phenomena. |
