In an image forming apparatus, a controller allows selection of one from a first setting mode and a second setting mode at an operating portion. The first setting mode allows operating conditions to be set at the operating portion. The second setting mode allows only some of the operating conditions to be set at the operating portion. If the second setting mode is selected at the operating portion, an operating condition settable in the second setting mode is set, and then the first setting mode is selected at the operating portion, the controller makes a setting of the operating condition having been set while the second setting mode is selected reflect in an operating condition to be set in the first setting mode.
