Image forming apparatus

An image forming apparatus comprising:

• a sheet stacking portion on which a sheet is stacked;
• an image forming portion configured to form an image on a sheet fed from the sheet stacking portion;
• a detection portion configured to detect a position, in a sheet width direction orthogonal to a sheet conveyance direction, of a sheet being fed from the sheet stacking portion to the image forming portion;
• a storage configured to store position information of a sheet in the sheet width direction;
• and
• a controller configured to control a job in which a sheet is fed from the sheet stacking portion and the image forming portion forms an image on the sheet,
• wherein the controller is configured to
• cause the storage to store the position information based on a position of a sheet detected by the detection portion during execution of the job, and
• if sheet information of a sheet used in a previous job is matches sheet information of a sheet used in a current job, cause the image forming portion to start formation of an image to be formed on a first sheet, before a position of the first sheet is detected by the detection portion, based on the position information stored in the storage in the previous job.
