Abstract
An image forming apparatus includes a belt; a plurality of rollers for stretching the belt; a mechanism for generating a force, at an end portion of the belt, in a direction in which lateral deviation of the belt is corrected; a forming device for forming a toner image on the belt; a first sensor capable of detecting a density of the toner image formed on the belt on one end side of the belt; a second sensor capable of detecting the density of the toner image formed on the belt on the other end side of the belt; and a control device for selecting one of the first and second sensors which provides smaller variation in a result of detection when the belt is free from the toner image, and for controlling an image forming condition of the forming device on the basis of a detection result of the density of the toner image by the selected sensor.
