Claim Text:
1. An image forming apparatus comprising: an image forming unit configured to form an image on a recording medium; a first rotation member configured to heat the recording medium on which the image has been formed; a second rotation member; a pressurization unit configured to apply pressure on the first rotation member or the second rotation member so as to apply pressure on a nip portion formed by the first rotation member and the second rotation member; a cam configured to receive pressure applied from the pressurization unit according to a rotational position of the cam, and change a pressurizing force applied to the first rotation member or the second rotation member; a DC motor configured to drive the cam to rotate; and a control unit configured to, in a first mode in which the cam rotates from a first rotational position to a second rotational position by passing through a third rotational position without stopping at the third rotational position, control the DC motor such that a rotational speed of the DC motor reaches a first target rotational speed, and in a second mode in which the cam rotates from the third rotational position to the second rotational position without passing through the first rotational position, control the DC motor such that the rotational speed of the DC motor reaches a second target rotational speed lower than the first target rotational speed, wherein a rotational angle from the first rotational position to the second rotational position is larger than that from the third rotational position to the second rotational position, and p
