摘要： Toner image forming means for forming toner images having chromatic colors of Y, M and C, respectively, are disposed on one side of an intermediate transfer belt, while disposing toner image forming means for forming a black toner image on the other side of the intermediate transfer belt, alone and on a most downstream side of all the toner image forming means. Further, when a toner image on the intermediate transfer belt includes toner having a reverse polarity, a transfer or developing process is controlled to reduce electrostatic attraction force acting on an image carrier, thus providing a color image forming device having a main body reduced in size and capable of faster image formation of a monochromatic image which is more frequently used, and of efficiently forming a color image by suppressing a back-transfer phenomenon and improving color reproducibility.

摘要： An image forming apparatus and a method for cleaning a photoreceptor are realized that allow cleaning a surface of the photoreceptor to eliminate foreign substances adhering thereto, without using a special abrasive sheet. A recording sheet is fed and brought into contact with photoreceptors of all photoreceptor drums. The recording sheet is stopped by causing the vicinity of a rear end of the recording sheet to be sandwiched between a pair of registration rollers. Then, the photoreceptor drums are rotated. By this way, the cleaning is carried out to the photoreceptor.

摘要： An object of the invention is to make an exact judgment on suitability of a replaceable component such as a toner supplying container with use of an existing mechanism of an image forming apparatus, without additionally providing a data storage component designed for a consumable product which is detachably attached to the apparatus, or a data reading component to be placed in the image forming apparatus main body. In an incorporated control section, a specific part of a replaceable component, which is placed on an original platform prior to being loaded into the apparatus, is optically scanned to read image information, and, based on the reading result, whether or not the replaceable component is suitable for the image forming apparatus is judged.
