description A detecting device, which is included in an image forming apparatus, includes a detector configured to optically detect at least one of a position of a sheet, a position of an image formed on the sheet, and the image formed on the sheet, and a rotary body disposed at a position opposed to the detector and having a shaft, the rotary body being rotatable about the shaft in a sheet conveying direction of the sheet. The sheet is conveyed to space between the detector and the rotary body. The rotary body has a reference plane on an outer circumferential surface, a line formed on the reference plane and extending in a width direction perpendicular to the sheet conveying direction. The detector detects the line on the reference plane while the rotary body is rotating when the sheet does not intervene between the detector and the rotary body.
