Abstract: An image forming apparatus includes light sources, a light intensity controller, an optical writing unit, a controller, and an image forming unit. The light sources are switchable between activated and deactivated conditions according to supplied image data. The light intensity controller controls light intensity of the light sources. In the optical writing unit, light beams output from the light sources are deflected in a main scanning direction. The controller sets a given number of light sources to activated condition to write a latent image on an image bearing member according to an image forming line speed. The controller instructs the given number of light sources to emit light beams onto an image area on the image bearing member, and instructs all of the light sources to emit light beams at a blank area on the image bearing member to execute a light intensity control for all of the light sources.

Abstract: A write reference signal generating unit uses horizontal synchronization signals output from BD sensors to generate, for each laser scanning unit of respective image forming units, a main scanning write reference signal for irradiating laser light from a semiconductor laser every other predetermined number of reflective surfaces when photosensitive drums are driven to rotate at a second speed of rotation which is slower than a standard speed of rotation. A phase adjustment unit adjusts the phase of a control signal for driving a polygonal mirror, which is output to a polygon motor of each image forming unit, on the basis of a relative time difference between image write timings of the respective laser scanning units as measured by a time difference measurement unit.

Abstract: Disclosed herein is a method of controlling a motor in an image reading apparatus. It may be possible to optimize the drive current of the motor for driving the movement of the scanning module by using information associated with, for example, the time it takes for the scanning module to return to a home or rest position after the scanning module is moved from the home position to a predetermined position. Such optimized drive current can result in improvements in the reading performance of an image by the image reading apparatus and reduction of power consumption.

Abstract: An apparatus to control color registration and image density and a method of calculating a color registration error. The apparatus includes registration marks formed on a transfer belt such that each of the registration marks includes a scan direction component and a slanting direction component at an angle with respect to both the scan direction and the cross-scan direction. The apparatus further includes image density marks formed on the transfer belt, having predetermined image densities, and a registration and image density sensor provided above the registration marks and the image density marks to radiate beams onto the registration marks and the image density marks. The sensor receives beams reflected from the registration marks and the image density marks to produce detection signals, and obtains registration information and image density information from the detection signals. Accordingly, X-offset, Y-offset, printing width error, and skew can be simultaneously compensated for using a single apparatus.
