Abstract:
1. An image forming apparatus for forming images using a first image forming condition which forms an image with a first resolution level and first line speed, and a second image forming condition which forms an image with a second resolution level and second line speed, the second resolution level being finer than the first resolution level and the second line speed being slower than the first line speed, the image forming apparatus comprising: a density adjustment unit to conduct a first image forming density adjustment for adjusting an image forming condition and a second density adjustment for adjusting an exposure time per pixel based on a measurement result of a plurality of half-tone patterns, in which each pattern has a different exposure time per pixel, wherein the density adjustment unit conducts the second density adjustment for the second image forming condition before a printing operation shifts from a printing operation using the first image forming condition to a printing operation using the second image forming condition; and wherein when a first density adjustment is scheduled within a given time span before or after the printing operation shifts from a printing operation using the first image forming condition to a printing operation using the second image forming condition, one of the scheduled first density adjustment and second density adjustment is shifted in time such that the second density adjustment occurs after the first density adjustment.
