Abstract

An image forming apparatus including: a joint head in which a plurality of heads (±, ²), each having a plurality of nozzles arranged in a predetermined direction, are arranged in a nozzle arranging direction, and end portions of the heads adjacent to each other overlap; an overlap processing unit that distributes recording dot pattern data used for forming dots by using nozzles of an overlapping portion (±/²) of the heads (±, ²) adjacent to each other out of recording dot pattern data to the nozzles of the recording head (±, ²) adjacent to each other; a first tone correcting unit that performs tone correction, by a first correction characteristic determined in advance for each of the heads (±, ²), on recording dot pattern data used for forming dots using the nozzles other than the overlapping portion, out of the recording dot pattern data; and a second tone correcting unit that performs tone correction by a second correction characteristic on recording dot pattern data used for forming dots by using the nozzles of the overlapping portion (±/²), wherein the second correction characteristic is an intermediate correction characteristic of the first correction characteristics of the heads (±, ²) adjacent to each other.
