摘要： An image forming apparatus includes a photoreceptor and a charging member. The photoreceptor includes a long-shaped raw pipe and a photoconductive layer that covers a center portion of the raw pipe in a longitudinal direction and forms exposed parts at ends of the raw pipe in the longitudinal direction. The charging member is arranged in parallel to the photoreceptor through a gap. The charging member includes a long-shaped conductive support body and a resistance adjustment layer that covers a center portion of the conductive support body in the longitudinal direction, and charges the photoconductive layer. Besides, the charging member includes a gap keeping member and a discharge preventing part. The gap keeping member is provided at a position outwardly spaced from a photoconductive layer opposite area by a specified distance in the longitudinal direction of the conductive support body, contacts the exposed part, and keeps a gap between the resistance adjustment layer and the photoconductive layer. The discharge preventing part covers a separation area between the resistance adjustment layer and the gap keeping member in the longitudinal direction of the conductive support body, and prevents discharge from the exposed part to the separation area.

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.
