Abstract
An image forming apparatus comprises a recording head having a plurality of recording elements arranged in array, the recording head being utilized for recording a corrective image onto a recording material, an image reading device to acquire readout information by reading the corrective image, an carrying out section to conduct calculation to obtain a correction amount of recording characteristics, from the readout information acquired by the reading device, an image forming section to form an image onto the recording material by the recording head in which a recording characteristics of the plurality of recording elements are compensated based on the correction amount, and a controller to control the recording head so as to record the corrective image on to the recording material, wherein, the readout information in the carrying out section discriminates optical density unevenness caused by a factor not being associated with the recording head.
