Patent number: 6526252Abstract: An image forming apparatus and method cause a connecting/conveying device to convey a recovered toner from a cleaner part to a recovered toner housing to house therein the recovered toner, and cause a controller to control a recovered toner supply and a new toner supply in accordance with a toner concentration ratio in a developing device, which is detected by a toner concentration ratio detector, to supply the recovered toner, which is stored in the recovered toner housing, and the new toner, which is stored in the new toner housing, to the developing device. The controller separately controls the recovered toner supply and the new toner supply in accordance with the contents detected by the toner concentration ratio detecting means, to cause to change the combination of the amounts of the recovered toner and new toner to be supplied to the developing device.Type: GrantFiled: October 15, 2001Date of Patent: February 25, 2003Assignee: Toshiba Tec Kabushiki KaishaInventors: Shinichi Itoh, Tetsuo Katoh, Tatsuyuki Miura, Seiji Tsuzuki

Patent number: 6323889Abstract: An exposure apparatus emits a number of laser beams to the predetermined positions on a single photosensitive drum. Galvano-mirrors are employed for controlling the distances between the laser beams in the main scanning direction and the sub-scanning direction. The angles of the mirrors of the galvano-mirrors are adjusted in such a manner as to eliminate the adverse effects caused by a drift, such as variations in the viscosity of the dampening agent of a mirror driving mechanism and variations in the magnetic force generated by a magnetic circuit. Without such adverse effects, the laser beams can be guided accurately to the predetermined positions on the photosensitive drum. The angles of the mirrors are monitored by checking whether the laser beams are incident on the predetermined positions on the detection areas of a beam position sensor.Type: GrantFiled: November 12, 1999Date of Patent: November 27, 2001Assignees: Toshiba Tec Kabushiki Kaisha, Kabushiki Kaisha ToshibaInventor: Tatsuyuki Miura

Patent number: 6285388Abstract: When the image-forming modes are switched over, the difference between the scan speeds of image-forming modes before and after the mode switching is checked. If the difference is not less than a predetermined set value, the adjustment of a laser beam is executed first, and then image formation is started. If the difference between the scan speeds of image-forming modes before and after the mode switching is less than the predetermined set value, the image formation is started immediately without making adjustment of the laser beam.Type: GrantFiled: March 14, 2000Date of Patent: September 4, 2001Assignee: Toshiba Tec Kabushiki KaishaInventor: Tatsuyuki Miura

Patent number: 5124744Abstract: An image forming apparatus employs a control means for controlling a driving means such that the current supplied to the driving means is varied between the interval from the end of the acceleration of a scanning means in the advancing direction to the start of the returning of the scanning means and the interval from the start of the returning of the scanning means to the end of the acceleration of the scanning means in the advancing direction. Due to the employment of this control means, a large torque is produced by a moving means for the scanning means during the interval from the start of the returning of the scanning means to the end of the acceleration of the scanning means in the advancing direction. Accordingly, vibrations are suppressed at the end of the returning movement of the scanning means.Type: GrantFiled: August 22, 1990Date of Patent: June 23, 1992Assignee: Kabushiki Kaisha ToshibaInventors: Masahiko Ogura, Kazuhiro Ikemori, Tatsuyuki Miura
