Patent number: 5797075Abstract: A developing apparatus includes toner powder in the form of fine colored powder, a toner carrier, and a frictional controlling member for contacting under a pressure with the toner carrier under pressure to frictionally charge the toner powder and form a thin toner layer on the toner carrier. The toner carrier on which the thin toner layer is formed is rotated so as to transport the thin toner layer to an opposing location on a toner image carrier on which an electrostatic latent image is formed to convert the electrostatic latent image into a visible image. The developing apparatus includes a toner supply roller disposed in rotating contact with the toner carrier at a side of the toner carrier, the frictional controlling member being provided at a position in contact with the toner carrier downstream of the toner supply roller; and a rotatable toner scraping member is provided in a neighboring relationship below the toner supply roller and the frictional controlling member.Type: GrantFiled: March 11, 1997Date of Patent: August 18, 1998Assignee: Hitachi, Ltd.Inventors: Masahiko Saito, Toru Miyasaka, Kazushige Oonishi, Shoji Takeya, Isamu Terashima, Tetsuro Akasaki, Tadashi Okano

Patent number: 5761568Abstract: An electrophotographic imaging apparatus includes a toner image holding body, a transcription unit for transcribing the toner image on the toner image holding body onto a recording medium, and a conveyor for conveying a recording medium toward the toner image holding body and transcription unit. A judging device will judge whether printing is of a first page or not and if it is decided that printing is to be performed on a first page, a first measuring device will measure the electrical characteristic of the toner image holding body prior to the feeding of a recording medium and a transcription voltage will be set depending of this measured result. Thereafter, the recording medium will be conveyed toward the transcription unit where the electrical characteristics of the non-printing region on the recording medium will be measured via a second measuring device and the transcription voltage will be further adjusted.Type: GrantFiled: December 27, 1996Date of Patent: June 2, 1998Assignee: Hitachi, Ltd.Inventors: Hideyuki Haragakiuchi, Hiroyuki Tadokoro, Nobuaki Fukasawa, Akira Sasaki, Isamu Terashima, Masashi Yamamoto

Patent number: 5602578Abstract: An intermediate transcription drum is supported so as to be driven in contacting relationship with a photosensitive belt. The rotating speed of the photosensitive belt driving motor is controlled by a control unit such that one rotation cycle of the intermediate transcription drum becomes a given cycle. An adjustment of the speed control data for the photosensitive belt driving motor is performed in the interval between electrostatic latent image forming. Thereby, a speed difference between the photosensitive belt and the intermediate transcription drum does not occur, and a plurality of the toner images can be transferred and accurately superposed onto the outer surface of the intermediate transcription drum.Type: GrantFiled: March 3, 1994Date of Patent: February 11, 1997Assignee: Hitachi, Ltd.Inventors: Michio Sumiyoshi, Akira Sasaki, Hiroyuki Tadokoro, Takeshi Kato, Isamu Terashima, Junichi Matsuno, Masaru Nakano
