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： 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： According to one embodiment, an image forming apparatus includes a first image forming unit, a second image forming unit, and an intermediate transfer medium. The first image forming unit includes at least one image bearing member on which a first image is formed. The second image forming unit includes an image bearing member on which a second image is formed. The first image is primarily transferred onto the intermediate transfer medium. When the intermediate transfer medium is moved to a first position, the first image is secondarily transferred onto the image bearing member of the second image forming unit and tertiarily transferred onto a transfer medium from the image bearing member. When the intermediate transfer medium is moved to a second position, the second image is transferred onto the transfer medium from the image bearing member of the second image forming unit.
