Image forming apparatus

An image forming apparatus, comprising:

• a plurality of sheet detection units provided at different positions along a sheet width direction orthogonal to a conveyance direction of a sheet, the plurality of sheet detection units being configured to detect the sheet conveyed on a conveyance path;
• a first determination unit configured to determine, by using the plurality of sheet detection units, a presence or absence of a sheet being conveyed in each of a plurality of regions sectioned in the sheet width direction;
• a second determination unit configured to determine, based on input image data, a presence or absence of an image to be formed in each of the plurality of regions;
• a third determination unit configured to determine, based on a determination result of the first determination unit and a determination result of the second determination unit, whether or not the image to be formed on the sheet being conveyed is to be formed with a deviation from the sheet in the sheet width direction;
• and
• a control unit configured to control an image forming operation in accordance with a determination result of the third determination unit.
