摘要： An image forming apparatus that forms an image using a photoconductor body includes a switching unit which effects switching between a state in which a cleaner is operated for the photoconductor body, and a state in which the cleaner is not operated for the photoconductor body. A control unit is provided which controls a setting change of an image formation condition between a case where the cleaner is operated by the switching unit, and a case where the cleaner is not operated by the switching unit. The switching unit includes a detection unit which detects the kind of paper on which an image is formed, and the switching unit switches on/off the cleaner in accordance with a detection result of the detection unit.

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.
