An image forming apparatus, comprising:
- an image forming unit configured to form an image on a sheet;
- a measuring unit configured to measure reflected light from the sheet;
- a backup roller configured to convey the sheet while pressing the sheet toward the measuring unit;
- and
- a generating unit configured to control the backup roller to convey the sheet while pressing the sheet toward the measuring unit, control the measuring unit to measure the reflected light from the sheet conveyed by the backup roller, and generate profile data corresponding to measurement results of the reflected light from a plurality of positions in a direction in which the sheet is conveyed.
A method of controlling an image forming apparatus,
- the image forming apparatus including:
- an image forming unit configured to form an image on a sheet;
- a measuring unit configured to measure reflected light from the sheet;
- and
- a backup roller configured to convey the sheet while pressing the sheet toward the measuring unit,
- the method comprising:
- conveying the sheet by the backup roller;
- measuring, by the measuring unit, the reflected light from the sheet conveyed by backup roller;
