Claim:
An image forming apparatus which forms an image on a sheet comprising: a sheet feeding tray to store a sheet; an image forming section to form a toner image on the sheet fed from the sheet feeding tray; a fusing section to fuse the toner image on the sheet; a controlling section to perform cleaning of the fusing section when a sheet has been nipped in the fusing section at a time of occurrence of a jam by passing a sheet from the sheet feeding tray through the fusing section after the jam is relieved; an operating section to set an allowed condition including a sheet type and basis weight of an allowed sheet to be used for cleaning the fusing section; and a memory section to store the allowed condition including the sheet type and basis weight set on the operating section, wherein the controlling section determines whether or not the sheet feeding tray stores a sheet which satisfies the allowed condition stored in the memory section when cleaning of the fusing section is performed, and when the sheet feeding tray stores the sheet which satisfies the allowed condition, the controlling section selects the sheet feeding tray and controls the sheet feeding tray to feed the sheet from the selected sheet feeding tray and controls the fusing section to pass the sheet through the fusing section.
