Abstract: A color image forming apparatus includes a coordinate conversion part, which converts a ordinate value, for executing a misregistration correction in the unit of a pixel; a gradation conversion part, which converts a gradation level, for executing a misregistration correction in a unit less than a pixel; and a judgment part, which detects a feature of the image and judges whether or not to execute the misregistration correction in a unit less than a pixel by the gradation conversion part. The judgment part compares the gradation level in an object pixel and a pixel adjacent in a sub-scanning direction, thereby judging whether or not to execute the misregistration correction in a unit less than a pixel. Thus, the invention enables to distinguish an image to be subjected to the registration correction in a unit less than a pixel and an image not to be subjected to such correction in a simple manner and also in consideration of the image color.

Abstract: A scan-beam detection signal Hsync provided by horizontal synchronous sensors 60A, 60B is inputted to a drive signal controlling section 10Y as a drive period signal related to a drive period of a deflective mirror. The drive signal controlling section 10Y controls a drive signal Sd such as to establish a predetermined relationship between a phase of a reference signal Sr and a phase of the horizontal synchronous signal Hsync, whereby a deflector 65 is allowed to operate in synchronism with the reference signal Sr. Therefore, a latent-image forming position with respect to a sub-scan direction Y is adjusted by way of the phase adjustment between the reference signal Sr and the horizontal synchronous signal Hsync, so that a linear latent image is prevented from deviating with respect to the sub-scan direction Y.

Abstract: An image forming apparatus includes a light source, a deflector, beam detectors, a clock generator, a measurement mechanism, a frequency corrector, and a phase corrector. The light source illuminates in response to image data. The deflector deflects an optical beam into a scanning beam. The beam detectors including first and second beam detectors detect the scanning beam. The clock generator generates writing clock signals. The measurement mechanism measures a count number of the writing clock signals generated during a period between the scanning beam is detected by the first and second beam detectors. The frequency corrector corrects a frequency of the writing clock signals such that the count number measured becomes substantially equivalent to a predetermined number. The phase corrector varies a phase of the writing clock signals such that the count number is substantially constant before and after the phase of the writing clock signals is varied.
