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.

An image forming apparatus includes a plurality of latent image bearers, a latent image writer, a plurality of developing units, a primary transfer unit, a secondary transfer unit, an adjuster, a pattern image formation controller, a color deviation detector, a color deviation correction controller, and an image-formation-mode setting unit. The latent image writer writes latent images to the latent image bearers. The plurality of developing units develops the latent images of the latent image bearers and form toner images of different colors. The primary transfer unit transfers the toner images on the latent image bearers to an intermediate transferer. The secondary transfer unit transfers the toner images from the intermediate transferer to a sheet. The adjuster causes the intermediate transferer and the secondary transfer unit to be in a contact state or a separated state. The pattern image formation controller forms a pattern image on the intermediate transferer via the latent image bearers to detect color deviation. The color deviation detector detects the color deviation of the pattern image borne on the intermediate transferer. The color deviation correction controller executes color deviation correction control in the separated state. The image-formation-mode setting unit sets a normal linear-velocity image formation mode in which an image is formed at a normal linear velocity and at least one non-normal linear-velocity image formation mode including a low linear-velocity image formation mode in which an image is formed at a low linear velocity slower than the normal linear velocity. A plurality of image formation velocities including the normal linear velocity and the low linear velocity is set, and an execution timing of the color deviation correction control in image formation at the normal linear velocity and an execution timing of the color deviation correction control in image formation at the low linear velocity are set independently from each other.

A sheet processing device includes a stapling tray, a rear-end clamp, and a stapler that staples sheets while the rear-end clamp is clamping the sheets. In response to a start signal, the stapler moves to a position where the stapler does not interfere the rear-end clamp while being closest to a stapling position. When the last sheet of a sheet bundle to be stapled is conveyed into the stapling tray, timing at which the stapler moves to the stapling position is determined according to a preset condition.
