1. An image forming apparatus comprising:
a nozzle head in which a plurality of nozzles that ejects ink is arranged in a first direction;
a moving mechanism that moves a recording medium relative to the nozzle head;
an image acquirer that acquires image data;
a quantization processor that quantizes density of pixels forming an image on a basis of the image data;
a grouping processor that groups a plurality of adjacent pixel positions into one group in the data that is quantized; and
a rearrangement processor that rearranges a quantized pixel value at each pixel position in the group that is grouped, wherein
the grouping processor
groups such that a direction intersecting the first direction is set to a second direction, arrangement of a plurality of groups in the first direction is set to a row, a plurality of rows is arranged in the second direction, and a row in which an initial position of the row is different at least by one pixel is included.
