摘要： A color image forming apparatus includes an image bearing member for carrying an electrostatic latent image, a plurality of developing devices for developing the electrostatic latent image, a supporting member for moving the developing devices sequentially to a developing position opposing the image bearing member, and a detecting device for detecting developer remainder in the developing device. In addition, a determining portion determines the developer remainder. In the developing device in which the detecting operation is effected after the developing operation, the determining portion determines the developer remainder from the information relating to the detected developer remainder. In the developing device of the developing devices for which the detecting operation is effected before the developing operation, the determining portion determines the developer remainder from the information relating to the detected developer remainder and a deduced consumption amount.
