Claim Text:
1. An image forming apparatus comprising: a photosensitive member configured to be rotated; an irradiating unit configured to irradiate the photosensitive member that is charged with light corresponding to image data, thereby forming an electrostatic latent image on the photosensitive member; and a process unit configured to form a nip portion with the photosensitive member, wherein 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 irradiating unit, 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.
