摘要： An image forming device includes a plurality of developing devices and a photosensitive drum. Each of the developing devices includes a developer carrying roller. One of the developing devices is moved to a developing position confronting the photosensitive drum which is formed with a latent image. A first developing bias including a d.c. component and an a.c. component is applied to the developer carrying roller and developer on the developer carrying roller is rendered in contact with the latent image on the photosensitive drum so that the latent image is developed. On the other hand, when the developer on the developer carrying roller comes in contact with and separates from the photosensitive drum due to the movement of the developing device, a second developing bias is applied to the developer carrying roller. The second developing bias generates an electric field where the developer on the developer carrying roller is more reluctant to move toward the photosensitive drum as compared with the first developing bias. The second developing bias may include only a d.c. component.

摘要： A developing device is provided which has a developing chamber, a toner container and a hopper portion all provided together on a revolving holding mechanism. A drive device is provided to revolve the driving mechanism and a stopping device is provided to stop this holding mechanism revolving movement at least to provide the developing chamber in a facing relationship to an image carrier. Moreover, the relative position of the toner chamber and the hopper portion are such that the hopper portion can be replenished with toner from the toner chamber at least once during a complete rotation of the revolving holding mechanism. Replenishment can occur independently of image formation, while the holding mechanism is revolving or during a pause in the revolving of the holding mechanism.

摘要： In an image forming apparatus, a rotary developing device has a developing unit in which a plurality of developing chambers are arranged around an axis of rotation. The developing unit is rotated about the axis to bring one of the chambers to a developing position where an image carrier is located. In each of the chambers, part of a developer removed by a doctor blade is received by a guide and then released from the guide into the chamber. This part of the developer is agitated in the vertical direction together with the developer existing in the chamber by the rotation of the device. As a result, the developer is agitated and charged in a desirable manner.

摘要： An image forming apparatus having a rotary developing device or revolver in which a plurality of developing sections are defined. The revolver is rotated over a target position by a first drive source, then returned by a second drive source producing a moment acting in the opposite direction, such as due to the drive of one of the developing sections, and then positively stopped by a positioning mechanism. The revolver is, therefore, accurately positioned at the target position without regard to, for example, irregularities in a motor for driving the revolver.

摘要： In an image forming apparatus, a rotary developing device or revolver has a plurality of developing sections each storing a developer of particular color thereinside. The revolver is rotatable to sequentially move the developing sections to a preselected developing position so as to develop toner images sequentially formed on an image carrier. Toner cartridges are each removably mounted to the respective developing section. Only one of the cartridges located at a preselected replacing position can be pulled out and replaced. A toner cartridge is prevented from being accidentally mounted to the developing section located at the replacing position and whose cartridge has already been replaced.
