    • PURPOSE: An image forming apparatus is provided to detect surface conditions of a recording sheet based on a surface image formed by an image capture device and to control image forming conditions based on the result of recording paper surface detection. CONSTITUTION: A control unit(10) instructs an exposure scanner unit to perform exposure according to a received image signal to form an electrostatic latent image on the surface of a photosensitive drum which is a photosensitive member charged to a fixed potential by a charging roller. A driving force of a drive motor is transmitted to the photosensitive drum to rotate it clockwise in synchronization with the image forming operation. A developer unit is a unit for developing the electrostatic latent image to make it visible. The developer unit is provided with a development sleeve to which a developing bias is applied to make visible the electrostatic latent image. An intermediate transfer belt in contact with each of the photosensitive drums rotates counterclockwise synchronizing with the rotation of each of photosensitive drums at the time of color image forming. Color toner images developed on respective photosensitive drums are transferred onto an intermediate transfer belt(24) in succession and layered on top of one another by the action of a primary transfer bias applied to primary transfer rollers, thus producing a multi-color toner image on the intermediate transfer belt. Then, the multi-color toner image formed on the intermediate transfer belt is conveyed to a secondary transfer nip portion including a secondary transfer roller pair(25). A fixing unit(21) melts and fixes the transferred multi-color toner image onto the recording sheet while conveying the recording sheet. A cleaning unit(28) removes residual toner from the intermediate transfer belt to clean the belt, and the removed residual toner is stored in a cleaner container(29) as waste toner.
