Abstract
Provided is a control unit that executes a first mode in which a developer bearing member rotates with respect to an image bearing member at a first circumferential speed ratio, and a second mode in which the developer bearing member rotates with respect to the image bearing member at a second circumferential speed ratio greater than the first circumferential speed ratio. In the second mode, in a case where information indicating that output image data includes acquiring only a first pattern of first gradation, the control unit controls to apply a first transfer voltage, and, in a case where information indicating acquiring output image data that includes the first pattern and a second pattern of second gradation with lower density than the first gradation, the control unit controls to apply a second transfer voltage having an absolute value less than the first transfer voltage.
