Abstract
An image processing apparatus includes a beam corrector which corrects a gray level of each pixel in image data so as to reduce a density difference due to a misalignment in beam position of laser beams of a multibeam array. The beam corrector includes a calculator which detects an edge of an object between a pixel and adjacent pixels of the pixel in the image data and calculates an edge intensity of the edge. The calculator calculates a corrected gray level of the pixel from the calculated edge intensity and a correction value corresponding to a deviation in beam position of the laser beams emitted according to a gray level of the pixel.
