Abstract
An image forming apparatus includes: a photosensitive member configured to be rotated; scanning means for scanning, by light corresponding to image data, the photosensitive member that is charged, thereby forming an electrostatic latent image on the photosensitive member; and a contacting member in contact with the photosensitive member to form a nip portion. In a correction mode in which a shift of an image is corrected based on a detection result obtained by detecting, at the nip portion, an electrostatic latent image for correction formed on the photosensitive member by the scanning means, a width of the electrostatic latent image for correction is equal to or more than a width of the nip portion in a rotation direction of the photosensitive member.
