ABSTRACT:
An image forming apparatus includes a rotational body having a rotation shaft, marks provided on a circumferential surface of the rotational body at a predetermined positional interval each other, a rotational photoreceptor provided on the rotation shaft, a driving system to drive the photoreceptor, a light source to emit a light onto the marks, a line sensor having a plurality of pixels in a row in which each pixel outputs an electric signal in accordance with a light intensity of the light projected, an image formation lens to focus the light reflected from the marks onto the plurality of pixels of the line sensor, a detector to detect a rotational information of the photoreceptor on the basis of the electric signal obtained by the line sensor. The apparatus further includes a control circuit to control the drive system on the basis of the rotational information detected by the detector to control a rotation of the photoreceptor.
