Abstract
An image forming apparatus includes a recording head including a plurality of nozzles for ejecting recording liquid to perform image formation on a recording medium; and a correcting unit. The correcting unit is configured to divide the recording head by different division patterns each indicating that the recording head is divided into a plurality of segments by at least one different dividing point, correct input and output characteristics for each of the segments in each division pattern to calculate correction effect of the each division pattern, and determine one of the division patterns based on the calculated correction effects of the division patterns as a specified division pattern to correct input and output characteristics of the recording head.
