Abstract
An image forming apparatus includes a control portion. The control portion determines a developer near end when the residual amount of a developer is in a range from a first predetermined amount to a second predetermined amount, and determines a developer end when the residual amount of the developer is equal to or lower than the second predetermined amount. Besides, in a case where the control portion determines the developer end after a predetermined number of printings are executed in a developer near end state, the control portion supplies the developer from a developer supply device to a development device via a first supply opening, and in a case where the control portion determines the developer end after more than the predetermined number of printings are executed, the control portion supplies the developer from the developer supply device to the development device via a second supply opening.
