Abstract
An image forming apparatus includes a multi-color misalignment calculator that calculates an amount of multi-color misalignment of multiple color misalignment detection test pattern images based on position readings outputted by multiple test pattern image detectors, an image formation condition adjusting unit that adjusts an image formation condition of the image forming apparatus in accordance with the amount of multi-color misalignment of the multiple color misalignment detection test pattern images calculated by the multi-color misalignment calculator, and a process control unit that initiates a first multi-color misalignment correction control mode including a skew misalignment correction process and a second multi-color misalignment correction control mode excluding the skew misalignment correction process to correct multi-color misalignment of the multiple color misalignment detection test pattern images. A memory stores the amount of skew misalignment calculated by the multi-color misalignment calculator when the process control unit initiates the second multi-color misalignment correction control mode.
