Abstract
An image forming apparatus, including: a control portion that controls a conveying speed of recording materials when the recording materials pass through a nip portion; wherein the control portion, in a case of continuous sheet passing of the recording materials each having a smaller width than the recording materials each having a maximum width: executes, in a case where a representative value of the number of the recording materials having the smaller width for one operation of the continuous sheet passing is smaller than a predetermined threshold, a first operating mode in which the conveying speed is controlled to a first speed; and executes, in a case where the representative value is the threshold or more, a second operating mode in which the conveying speed is controlled to a second speed lower than the first speed.
