An image forming apparatus includes a sheet-linear-velocity setting unit, an image-formation-rate changing unit, a detecting unit, and first and second correcting units. When printing is performed with a first sheet linear velocity, the first correcting unit performs misregistration correction according to a result of detection of a misregistration correction pattern image by the detecting unit. When the sheet-linear-velocity setting unit sets a second sheet linear velocity other than the first sheet linear velocity, the second correcting unit corrects an adjustment amount used in the misregistration correction performed by the first correcting unit, according to a ratio between first and second coefficients. The first coefficient indicates a ratio of an actual image formation rate at the first sheet linear velocity to an ideal image formation rate, and the second coefficient indicates a ratio of an actual image formation rate at the second sheet linear velocity to an ideal image formation rate. |
