PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of preventing stripe-like image disturbance caused by a decrease in a distance between sheets of paper during consecutive image formation. SOLUTION: In the image forming apparatus 100, the length of an intermediate transfer belt 1 from the primary transfer section T1d of a photoreceptor drum 1d for forming a black toner image to its secondary transfer section T2 is 60 mm. An interval between sheets is set according to the type of each recording material P, and image formation is carried out consecutively. However, if the calculated interval between the sheets is less than 73 mm, an interval of 73 mm is set regardless of the actual measurement. This prevents a toner image primarily transferred by the photoreceptor drum 1d from being disturbed by a change in the tension of the intermediate transfer belt 1 hit by a secondary transfer roller 3 at the instant that the recording material has passed through the secondary transfer section T2.
