Patent number: 7031631Abstract: An image forming apparatus includes a photosensitive member, an intermediate transfer material, a first transfer device, a second transfer device, a feed device, a refeed device, and a controller which executes selectively first and second modes, in which one or two images are formed on one round of the intermediate transfer material. An image, which should be formed on a refed sheet, is formed on a first half area on one round of the intermediate transfer material, and an image, which should be formed on a fed sheet, is formed on a second half area on one round, in a case of executing the second mode when performing image formation on both sides of a sheet. The first mode is executed before returning to the second mode after executing the first mode instead of executing the second mode when performing both side image formation.Type: GrantFiled: March 4, 2004Date of Patent: April 18, 2006Assignee: Canon Kabushiki KaishaInventors: Akihiko Sato, Shinichi Takata, Shigemichi Hamano, Toru Ono, Kenji Morita, Yushi Oka

Publication number: 20060072948Abstract: A motor drive control apparatus which are capable of improving quietness during operation of a motor without the need of modifying the motor driving circuit and without increasing the load torque on the motor. The motor drive control apparatus is connected to a pulse motor via a driving gear disposed on an output side of the motor, and a driven gear engaging the driving gear. The motor drive control apparatus performs drive control in which the motor is driven to transmit a driving force of the motor to a load via the driving gear and the driven gear, and performs position control in which the driving gear is moved by a predetermined amount such that a gap formed between the driving gear and the driven gear is reduced or removed, before the drive control is performed. The drive control is performed when a predetermined period of time has elapsed after the position control is performed.Type: ApplicationFiled: September 30, 2005Publication date: April 6, 2006Applicant: Canon Kabushiki KaishaInventors: Kazunori Miyake, Hiromichi Tsujino, Hidenori Sunada, Toru Ono

Patent number: 6947680Abstract: In a case where a rotating speed of an intermediate transfer member is reduced during the process of image formation, carriers may adhere to a photosensitive member before the rotating speed of the intermediate transfer member stabilizes. To cope therewith, in changing an image formation speed in accordance with a conveying speed of a recording material on completion of primary transfer, a developing rotary is rotated so as to keep any developing device off a developing position. Consequently, a situation in which the carriers adhere to an image bearing member can be avoided. At the same time, stopping a charging operation of a charger enables a longer service life of the image bearing member.Type: GrantFiled: March 8, 2004Date of Patent: September 20, 2005Assignee: Canon Kabushiki KaishaInventors: Yushi Oka, Akihiko Sato, Shinichi Takata, Shigemichi Hamano, Toru Ono, Kenji Morita

Publication number: 20040234282Abstract: When a plurality of toner containers mounted on a developing rotary is simultaneously determined as toner-absent toner containers, toner container replacement may not be efficient because toner containers are replaced at on replacement position. Therefore, when the toner containers mounted on the developing rotary are simultaneously determined as toner-absent toner containers, a toner container to be preferentially replaced is selected so as to be able to a replacement position by considering the usability.Type: ApplicationFiled: March 8, 2004Publication date: November 25, 2004Applicant: Canon Kabushiki KaishaInventors: Shigemichi Hamano, Akihiko Sato, Shinichi Takata, Toru Ono, Yushi Oka
