Abstract

An image forming apparatus, in accordance with the present invention, forms a color image on an image bearing member. The image forming apparatus includes a charging device for electrically charging the image bearing member, an exposing device for exposing a light beam on the image bearing member so as to form a latent image on the charged image bearing member corresponding to image data to be formed, and a developing device for developing the latent image formed on the image bearing member with a developing agent including toner. The image forming apparatus also includes a detecting device for detecting the amount of toner attached to the image bearing member by the developing device, an estimating device for estimating the amount of toner attached to the image bearing member in accordance with image data to be formed, and a control device for controlling the charging device, the exposing device and the developing device in accordance with the detected toner attaching amount and the estimated toner attaching amount so as to stabilize image density changes of the image formed on the image bearing member. Thereby, the image forming apparatus of the present invention can correct for …
