Abstract:
1. An image forming apparatus comprising: an image forming unit which forms a toner image made up of toners of plural colors; a belt which transfers to a sheet the toner image transferred to a belt surface by the image forming unit; a sensor whose detection area for the toner image is set closely to at least one end part in a direction of belt width orthogonal to a direction of belt surface movement, on the belt; and an image control unit which controls the image forming unit to form the toner image to be transferred to the sheet in a range different from the detection area in the direction of belt width, and to form plural alignment patterns for toner image alignment made up of toners of different colors from each other at a position which is within a range where the toner image is formed in the direction of belt surface movement and which overlaps the detection area in the direction of belt width.
