    摘要： A color image forming apparatus has a revolving type developing unit detachably installed therein. The revolving type developing unit includes a plurality of different color developing devices (420C,420M,420Y,420K) having a developing roller (41K,41Y,41M,41C) therein. Each of the developing rollers is movably mounted on the developing device so that a gap (Gp) between each of the developing rollers and a periphery of a photo-conductive drum (44) which is to be formed when the revolving type developing unit is set in the color image forming apparatus is enabled to be adjusted. A pulled-out supporter is enabled to be pulled out of the image forming apparatus for removably mounting said photoconductive drum and/or said revolving type developing unit.

    摘要： An image forming apparatus, incorporating a process cartridge, capable of determining optimum light exposure conditions suitable for both a charging potential and a film thickness of image bearing member, and performing the image formation even during the period from initiating to completing the setting of light exposure conditions. The image forming apparatus includes at least a charger unit, a light exposure unit, a developer unit, a detection unit, and a control unit. The detection unit is adapted to detect the total of rotation of the image bearing member. The control unit computes light exposure conditions to operate the light exposure unit based on an estimated thickness for a film of the image bearing member, which is calculated from the total of rotation obtained by the detection unit, and a first target uniform charging potential to control a uniform charging potential of the image bearing member, and to control the light exposure unit to be brought into the light exposure conditions.
