Abstract: To solve the problem in which: in a conventional image forming apparatus, when a pump unit is compressed to supply toner from a storage container to a developing unit, a load torque of a motor that drives to rotate the storage container is increased, and thus the rotation speed of the storage container does not become constant and the quality of an image formed on recording paper may be reduced.SOLUTION: In the present invention, when a pump unit is compressed, the duty ratio of a PWM signal to be input to a motor is increased by a predetermined amount. This can prevent excessive supply of toner from a storage container to a developing unit and prevent a reduction in quality of an image formed on recording paper.SELECTED DRAWING: Figure 8
