摘要： A CPU controls a shutter of a developing device so as to enable movement of a developer between a first chamber and a second chamber that store the developer. The CPU rotates a developing roller and mixers of the first and second chambers for a predetermined time T, and stirs and conveys the developer. Thereby, the developer is moved from the first chamber into the second chamber. The amount of movement of the developer is understandable from the rotational speed and shape of each mixer. Hence, the amount of developer, which is moved from the first chamber to the second chamber, is estimated in advance, and about half the developer in the first chamber is replaced.

摘要： In a color image forming apparatus of the invention, a developing roller of a developing device includes a magnet roller that is configured such that a developer supply pole, a developer convey pole and a developer release pole are properly arranged and fixed. The developer roller also includes an outer cylindrical roller that is formed of an electrically conductive material such as aluminum. A surface of the cylindrical roller is processed to have irregularities. Using the developing roller, simultaneous development/cleaning is executed. Thus, 100% of toner contributes to image formation, and no waste toner is produced. Post-transfer residual toner on a photoconductor body is efficiently recovered to the developing roller, and occurrence of an image defect such as development memory can be prevented.

摘要： There is provided a simply structured, cleanerless image forming apparatus capable of suppressing occurrence of filming without significant remodeling.An image forming apparatus 100 according to the present invention comprises a plurality of image forming units 100a, 100b, 100c, and 100d for forming toner images of corresponding colors on photoconductor drums 3a, 3b, 3c, and 3d according to a cleanerless system. These image forming units respectively have adhered toner film cleaners 1a, 1b, 1c, and 1d each of which touches a surface of the photoconductor and mechanically cleans the surface at every cleaning timing for cleaning the surface of the photoconductor. The adhered toner film cleaner does nothing during image formation, but cleans the photoconductor surface only at cleaning timing when the image formation is complete for the specified number of sheets. Accordingly, it is possible to decrease filming without affecting the photoconductor's life.
