一連の画像形成動作の際に未使用となる画像形成ユニットについて、対応する像保持体の回転を維持しつつ、対応する前記現像ロールの回転及び前記除電手段による露光を停止させることを特徴とするカラー画像形成装置。 An image carrier that holds an electrostatic latent image on the surface, a charging unit that applies a predetermined charging bias to charge the surface of the image carrier to a predetermined potential, and exposes the surface of the image carrier. And an exposure unit that forms a desired electrostatic latent image, and a developing roll that is rotatably disposed and is opposed to the image carrier, and is formed on the image carrier by applying a predetermined development bias. Development means for converting the electrostatic latent image into a toner image, transfer means for transferring the toner image formed on the image carrier to a recording medium, and residual toner on the image carrier after transfer to a plate-shaped cleaning blade A color image forming apparatus comprising a plurality of image forming units each having a cleaning means for cleaning in step (a) and a charge eliminating means for uniformly exposing the surface of the image carrier after transfer to uniform the residual potential,
An image forming unit that is not used in a series of image forming operations is configured to stop the rotation of the corresponding developing roll and the exposure by the charge eliminating unit while maintaining the rotation of the corresponding image holding member. Color image forming apparatus.
