In the image forming apparatus a binary-digitizing section compares inputted multi-valued image data with a threshold value and converts the image data to binary data, a template matching section determines whether smoothing is to be executed or not by comparing the binary-digitized data with the template data, a smoothing section converts the image data for a pixel determined as an object for smoothing to multi-valued data, and a data selector selects and outputs the multi-valued pixel data when the image data is determined as an object for smoothing, or selects and outputs the original data when the image data is not an object for smoothing.

Image forming apparatus and image forming method

An imaging system includes a plurality of semiconductor lasers for emitting a plurality of laser beams for use in forming an image on a photosensitive member. A laser driver circuit is provided for each of the plurality of lasers, and a plurality of photodectors are also provided, each detecting the light intensity of the corresponding one of the laser beams emitted from the lasers. A light intensity stabilizing control circuit is provided to stabilize the light intensity of each of the plurality of laser beams using one of the detected light intensities as a reference and adjusting the light intensity of each of the other beams such that a difference between the reference and the light intensity of each of the other beams is within a predetermined range.
