    摘要: In an image forming apparatus having an auto power-off function, the durability of a roller of a heat fusing member or the like is improved. Before a lapse of a specified time .DELTA.t from a time T at which an auto power-off timer stops time counting, a fusing roller is driven for the time .DELTA.t. By this operation, the fusing roller is consistently driven within the set time of the auto power-off timer, thereby reducing a continuous stress in a nip portion of the fusing roller.
