Patent number: 7280131Abstract: An image formation device changes the rotational rate of a polygon motor, i.e. the main-scanning rate, and selects one of pulse width conversion tables when an image formation is performed multiple times on a single sheet of transfer paper. The changing of the main-scanning rate is for preventing inconsistent sizes between a first recorded image and a second recorded image caused by shrinkage of transfer paper. The pulse width conversion tables allow the pulse widths to be modulated.Type: GrantFiled: December 19, 2006Date of Patent: October 9, 2007Assignee: Canon Kabushiki KaishaInventors: Naoto Yamada, Hajime Kaji, Yoshitaka Yamazaki, Junichi Noguchi, Takayuki Kawakami, Hajime Motoyama, Satoshi Ogawara, Yushi Oka, Akihito Mori

Patent number: 7196717Abstract: An image forming apparatus which is capable of eliminating density irregularities of an image formed caused by potential irregularities of the photosensitive member when the drum is irradiated by a beam of constant luminous intensity. A laser driver irradiates a beam modulated based on an image signal onto a photosensitive member. A current controller variably controls a driving current for driving the laser driver. A PWM pulse width converter modulates a pulse width of the beam based on the image signal. A potential sensor measures the potential of the photosensitive member after the photosensitive member is irradiated by a beam having a predetermined luminous intensity. A selector causes the current controller to correct the driving current based on low frequency components of irregularities of the potential and changes a modulation coefficient used for modulating the pulse width based on high frequency components of the irregularities of the potential.Type: GrantFiled: February 14, 2005Date of Patent: March 27, 2007Assignee: Canon Kabushiki KaishaInventors: Akihito Mori, Hajime Kaji, Naoto Yamada, Yoshitaka Yamazaki, Junichi Noguchi, Hajime Motoyama, Satoshi Ogawara, Yushi Oka, Takayuki Kawakami

Publication number: 20070059013Abstract: In an image forming apparatus including a fixing device that uses a pressure belt as at least one of two pressing members, a warm-up time and time for shifting to a standby state are reduced with simple control without increasing power consumption. The two pressing members are brought into a press-contact state by a contacting/separating mechanism and only heating means on the upper side is turned on. When the temperature of the upper pressing member increases to temperature near a target temperature corresponding thereto, the pressing members are driven to rotate. When it is detected by temperature detecting means on the lower side that the temperature of the lower pressing member increases to temperature near a target temperature corresponding thereto, the two pressing members are brought into a separated state by the contacting/separating mechanism.Type: ApplicationFiled: September 12, 2006Publication date: March 15, 2007Applicant: CANON KABUSHIKI KAISHAInventors: Akihito Mori, Nobuo Sekiguchi, Tadaaki Saida, Keita Takahashi
