1. An image forming apparatus for transferring an image onto a surface of a sheet at a transfer position on a conveying path, comprising:
a pair of conveying rollers configured to convey the sheet to the transfer position;
an image sensor formed to extend in a conveying width direction that intersects a conveying direction of the sheet, including a plurality of photoelectric conversion elements arranged in a line in the conveying width direction, and configured to read the sheet upstream of the transfer position; and
a rotary body formed to extend in the conveying width direction and disposed to face the image sensor with the conveying path interposed therebetween, wherein the rotary body includes a background portion configured to face a reading surface of the image sensor when the rotary body is at a first rotational position, and a cleaning portion configured to come into contact with the reading surface of the image sensor when the rotary body is at a second rotational position.
