It is to provide an image forming apparatus capable of reducing a processing time and of forming an image without high-temperature offset and defect of fixing when images are continuously formed. The image forming apparatus has number of sheets storing means for storing the number of passing sheets upon previous continuous-image-formation; counter means for counting a passing time from the end time of the continuous image formation; and a CPU for, when the images are continuously formed at this time, limiting the number of sheets image-formed at a first copying speed at which the number of sheets is large per unit time to a predetermined number of sheets, based on the number of recorded sheets and the passing time upon the previous continuous-image-formation and for, when the number of sheets is over the limited number of sheets, changing the first copying speed to the second copying speed at which the number of sheets per unit time is small.
