Abstract
An electrophotographic image forming apparatus that scans a surface of an image carrier with multiple beams emitted from a plurality of light emitting elements on a basis of image data of multiple colors including black comprises a bow corrector that performs electronic bow correction of image data of a predetermined color other than black in accordance with a bow characteristic of black; and a density smoothing processor that smoothens a density level difference of an image of the predetermined color subjected to the bow correction by a density smoothing process.

An electrophotographic image forming apparatus that scans a surface of an image carrier with multiple beams emitted from a plurality of light emitting elements on a basis of image data of multiple colors including black, the apparatus comprising:
- a bow corrector that performs electronic bow correction of image data of a predetermined color other than black in accordance with a bow characteristic of black;
- and
- a density smoothing processor that smoothens a density level difference of an image of the predetermined color subjected to the bow correction by a density smoothing process.
An electrophotographic image forming apparatus that scans a surface of an image carrier with multiple beams emitted from a plurality of light emitting elements on a basis of image data of multiple colors including black, the apparatus comprising:
- a density correction processor that performs density correction of an image by inter-face light intensity correction;
- and
- one or more controllers that change a light intensity correction amount of the density correction processor in accordance with a distribution state of inter-face exposure segments.
An electrophotographic image forming apparatus that scans a surface of an image carrier with multiple beams emitted from a plurality of light emitting elements on a basis of image data, the apparatus comprising:
- a bow corrector that performs electronic bow correction of image data;
- a density smoothing processor that performs image slide on the image data subjected to the bow correction at a micro level and performs a density smoothing process;
- a density correction processor that performs density correction on the image data subjected to the bow correction by light intensity correction in such a manner that a density level difference does not occur in a halftone image due to an influence of reciprocity failure in an inter-face exposure segment;
- and
- one or more controllers that cause the density smoothing processor to perform processing with a grayscale cycle of a dither pattern as a cycle of a reference image slide.
