Abstract

In an image forming apparatus, a plurality of light emitting portions arrayed in an array direction. A lens array has a length in the array direction longer than a length in a direction orthogonal to the array direction. A controller is configured to perform: converting a reference printing pattern including a plurality of first linear patterns to a detection pattern including a plurality of second linear patterns, each of the plurality of first linear patterns forming a first angle with respect to a reference line parallel to the array direction, each of the plurality of second linear patterns forming a second angle smaller than the first angle with respect to the reference line; forming a detection pattern image on a transfer medium; detecting a print density of the detection pattern image with a sensor; and setting an image formation condition according to the print density detected by the sensor.
