ABSTRACT:
An image forming apparatus is composed of an image holding component for holding an image, a first image forming device and a second image forming device for respectively forming a first image and a second image on a surface of the image holding component, a switching unit for switching a mode between a first mode and a second mode, the first mode being where the first image forming device and the second image forming device come into contact with the image holding component and the second mode being where the second image forming device and the image holding component do not come into contact and the first image forming device comes into contact with the image holding component, a detecting unit for detecting information concerning an image formed on the image holding component, and a modifying unit for modifying at least one of an image forming condition for the first image and an image forming condition for the second image in accordance with the information detected by the detecting unit. With this structure, the current mode is switched as necessary, so that needless wear and tear on the second image forming device is prevented. Also, the modifying unit modifies the image forming conditions as necessary, so that deterioration on a reproduced image caused by the mode switching is prevented. As a result, a high-quality image can be obtained.
