Publication number: 20050073572Abstract: A photo conductor and exposure integrally-formed type apparatus is of a drum type, and is rotated at a fixed speed in a clockwise direction. A residual toner attached to a surface of the photo conductor is removed by a cleaner, and a charging device applies a charge load uniformly to a surface of the photo conductor layer so as to charge the photo conductor layer. A light emitting layer exposes the photo conductor layer in a luminous area from an inner side, and forms a latent image on the photo conductor layer. The latent image formed on the photo conductor layer is developed by toner by a developing device, and forms an apparent image by the toner attached to the latent image. Further, the toner image appearing on the photo conductor layer is transferred on a recording medium by a transfer device. Accordingly, since no movement exists between an exposure point and an image forming point in the luminous area, an image deterioration caused by the movement is not generated.Type: ApplicationFiled: June 24, 2004Publication date: April 7, 2005Applicant: Hitachi, Ltd.Inventors: Masahiro Yagi, Taichiro Yamashita, Toru Miyasaka, Kenji Asuwa, Shintaro Yamada
