摘要： This invention can improve the appearance quality of a pamphlet produced by suppressing a swell of a folded sheet bundle and prevent a drop in productivity without enlarging the size of a sheet processing apparatus. A sheet bundle receiving position is changed depending on a sheet size and the moving direction of the press unit is changed corresponding to the sheet size of a conveyed sheet bundle. As a consequence, the enlargement of the sheet processing apparatus can be avoided without deteriorating productivity.

摘要： An image-forming apparatus includes a rotatable photoreceptor carrying a toner image thereon, a rotatable intermediate transfer member, a primary transfer device facilitating primary transfer of the toner image from the photoreceptor onto the intermediate transfer member, a secondary transfer device facilitating secondary transfer of the toner image from the intermediate transfer member onto a sheet, and a controller controlling rotation speed of the intermediate transfer member. The controller sets the rotation speed at a first speed during primary transfer. After primary transfer and a delay period, the controller changes the rotation speed to a second speed. The controller determines which rotation of the intermediate transfer member to change the speed.

摘要： 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.

摘要： In an image forming apparatus which forms an image by transferring, onto sheets fed by a feeding unit at the first feeding interval, a toner image formed on a photoconductor or intermediate transfer member, if the temperature of a fixing unit which fixes an image transferred onto a sheet falls outside a set temperature range, the sheet layout is changed to a feeding interval wider than the first feeding interval. Whether to perform adjustment processing is determined based on determination of an image forming condition. If the feeding interval is changed to a wider one in the feeding interval changing step during image formation and it is determined in the determination step to perform adjustment processing, toner patch images are formed in an area where no toner image is formed on the photoconductor or intermediate transfer member. The adjustment processing is performed based on reading toner patch images.

摘要： 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.
