Abstract
An image forming apparatus includes a photosensitive member having first and second areas at different positions at an axial end of the photosensitive member, the first and second areas not overlapping an image area in an axial direction of the photosensitive member; a detecting unit that detects an image; and a forming unit that forms a transfer-object image in the image area, the transfer-object image being transferred to a transfer area of continuous-form paper, the forming unit further forming first and second images in the first and second areas of the photosensitive member, respectively, the first image not being transferred to the transfer area but being detected by the detecting unit for use in an operation of controlling conditions for image formation, the second image not being transferred to the transfer area and not being used in the operation of controlling the conditions for image formation.
