More Information
Summary:The invention relates to an image processing apparatus and an image forming apparatus. A halftone processing unit (32) that performs halftone processing on the target image and generates a binary image corresponding to the target image; a multi-graying processing unit (33) performs: (a) a process in which a pixel containing a dot is used as a pixel of interest in the binary image, and (b) a process in which the presence or absence of a dot is determined from among a plurality of first outer peripheral pixels separated from the pixel of interest by a predetermined first distance and a plurality of second outer peripheral pixels separated from the pixel of interest by a predetermined second distance; and (c) deriving the gradation level of the pixel of interest from a plurality of predetermined gradation levels of 3 or more on the basis of the number of dots in the plurality of first outer peripheral pixels and the number of dots in the plurality of second outer peripheral pixels, and generating a multi-gradati
