Abstract
The image forming apparatus includes a plate movable up and down, a control cam that moves the plate up and down, a stepping motor that derives the control cam, a sheet feeding roller that contacts the sheet on the plate moved up by the control cam to feed the sheet held in contact with the feeding unit through rotation caused by drive from the stepping motor, and a control unit that controls the stepping motor. The control unit rotates the stepping motor at a first speed so that the control cam moves the plate up. After the sheet feeding roller is rotated, when the sheet feeding roller is stopped to stop the stepping motor, the control unit changes the rotational speed of the stepping motor from the first speed to a second speed.
