Abstract: An image forming unit forms a toner image on an image carrier using toner. A transfer unit transfers the toner image to a sheet. A cleaner removes, from the image carrier, residual toner that was not transferred to the sheet by the transfer unit. In a detection mode for detecting a part of the image forming apparatus causing a streak, a controller may control the image forming unit to form a pattern on the image carrier, control the transfer unit so that the pattern passes through a transfer position without transferring the pattern to the sheet, control the cleaner to remove the pattern on the image carrier, and control the transfer unit to transfer a residual streak from the image carrier to the sheet. The residual streak occurs from the pattern image by causing an error of the cleaner.
