Abstract

In an image forming apparatus a period between a first image forming operation and a second image forming operation is a non-image forming period, and a developing unit is moved from a second position to a first position in a moving operation after the developing unit is moved from the first position to the second position in the non-image forming period in a case in which the consumption amount of the toner is equal to or less than a predetermined threshold value in the second image forming operation. A length of the non-image forming period in a case in which the moving operation is executed in the non-image forming period becomes longer than in a case in which the moving operation is not executed.
