摘要： An image forming apparatus includes an image bearing member, a flexible changing member and a developing device. When a first area to be an image forming area of the image bearing member, is present in a nip portion, a superimposed voltage resulting from a direct current voltage and an alternating voltage having a peak to peak voltage smaller than an alternating voltage applied when a charging potential of the image bearing member is converged is applied to the charging member. When a part of a second area to be a non-image area of the image bearing member exists in the nip portion, a direct current voltage without an alternating voltage is applied to the charging member.

摘要： An image forming apparatus includes a flexible charging member, which forms a nip portion between itself and an image bearing member. The charging member charges the image bearing member and is applied with a voltage when the charging member at least charges the image bearing member for an image formation. The nip portion is provided with an electrically conductive particles developing device for developing an electrostatic image formed on the image bearing member with a developer. The developing device executes a developing operation and, at the same time, executes a collecting operation for collecting a residual developer on the image bearing member. The voltage is a superposed voltage with a direct current voltage and an alternating current voltage having a peak to peak voltage, which is less than a peak to peak voltage of the alternating current voltage applied to the charging member when the charging potential of the image bearing member converges under the condition that the charging member charges the image bearing member without the conductive particles.

摘要： An image forming apparatus has an image bearing member, a developing agent image formed on the image bearing member, and transferring device for transferring the developing agent image onto a recording member. The image bearing member is cleaned, and the developing agent removed therefrom is stored in a container. A detection is performed as to whether or not the quantity of developing agent in the container has reached a predetermined state, and once the result of such detection becomes positive, the number of prints made thereafter is counted. The result of the detection and the result of the count are stored in a memory along with the container, and the image forming operation is controlled in accordance with the stored information. In another embodiment, the memory is stored in an attachable cartridge. The attachable cartridge has an image bearing member, a charger, a developing device, and a cleaning device.

摘要： A color printer has multiple developing-agent-containing cartridges each having storage units, and a cartridge holding unit for rotatably holding the developing-agent-containing cartridges. With one of the multiple developing-agent-containing cartridges positioned at an image formation position, a latent image on an image carrying member is developed by the developing agent contained in the developing-agent-containing cartridge. An access position where the storage units of the developing-agent-containing cartridges are accessed is a position other than the image formation position. This provides an image formation device and a control method thereof whereby storage units provided to developing-agent-containing cartridges can be accessed in a precise manner.
