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： An image forming apparatus of the present invention includes a conveyer belt for conveying an image receiving medium toward an image carrier, an image transferring member for electrostatically transferring a developed image formed on the image carrier onto the image receiving medium conveyed by the conveyer belt by applying an electric charge through the back of the conveyer belt, and an adsorbing roller provided on the surface of the conveyer belt facing it for electrostatically adsorbing the image receiving medium to the conveyer belt. The electric resistance of the conveyer belt from a first position where the conveyer belt and the adsorbing roller are facing each other to a second position where the conveyer belt and the image carrier are facing each other is larger than the electric resistance between the image carrier and the image transferring member.

摘要： This apparatus forms a multiplex image on a sheet of paper conveyed on a conveyor belt through a plurality of image forming stations and prevents any misregistration between the images on the paper by using a first charger to charge the conveyor belt and a second charger for charging the paper on the conveyor belt. The first charger supplies the conveyor belt with an electrical charge of a predetermined polarity before the paper is supplied thereon. The second charger charges the paper on the conveyor belt with an electrical charge of a polarity opposite to the predetermined polarity.
