Abstract

An image forming apparatus includes an image forming section which transfers toner onto a latent image due to a difference of electrostatic potential to form a toner image, a transfer section which transfers the toner image onto a recording material directly or via an intermediate transfer body, a fixing section which passes the recording material carrying the toner image between a fixing rotation body and a pressurizing member contacted and pressed each other, and heats and pressurizes to fix the toner image, and a paper dust amount measuring section which measures an amount of paper dust adhering to the recording material. The image forming section forms an image pattern with high toner area coverage at a predetermined interval based on the measured amount of paper dust, and the fixing section fixes the image pattern with the high toner area coverage transferred onto a recording material.
