Abstract:
1. A color image forming apparatus including photosensitive members, charging units configured to charge the photosensitive members, light emission units configured to form an electrostatic latent image on the photosensitive member charged by being irradiated with light, and developing units configured to visualize a toner image by applying toner to the electrostatic latent image, corresponding to a plurality of colors, respectively, the color image forming apparatus comprising: a plurality of storage units corresponded to the plurality of colors, wherein information concerning a remaining service life of each of the plurality of photosensitive members corresponding to the plurality of colors is stored in each of the plurality of storage units, an acquisition unit configured to acquire information concerning a remaining service life of each of the plurality of photosensitive members; and a control unit configured to cause each of the plurality of the light emission units to execute normal light emission for visualizing the toner image onto an area where the toner image is to be visualized on the charged photosensitive member, and cause the plurality of light emission units to execute weak light emission onto a background area where the toner image is not to be visualized on the charged photosensitive member, the control unit controls the plurality of light emission units so that an exposure amount of the photosensitive members by executing the normal light emission is larger than an exposure amount of the photosensitive members by executing the weak light emission, wherein the control unit changes the amount of light for weak light emission by each of the plurality of the light emission units based on information concerning the remaining service life of each of the photosensitive member acquired by the acquisition unit.
