ABSTRACT:
An image forming apparatus includes a latent image bearing member and a developing portion having a plurality of developing devices provided facing the latent image bearing member, as well as an inputting portion for inputting an image signal, an auto-discriminating portion for automatically discriminating the kind of image input, and a control portion for changing between a first mode for executing monochrome image formation, a second mode for executing color image formation, and an auto-selecting mode for changing over between the first mode and the second-mode according to the discrimination of the auto-discriminating portion. In the auto-selecting mode, movement of a predetermined developing device to a predetermined position is started before the auto-discriminating portion makes the discrimination.
