摘要： In an image forming apparatus, process cartridge, and storage medium, if an image forming stop factor occurs in a cartridge of a certain color, image forming using a cartridge of another color is enabled to increase the utilization efficiency and operability of the image forming apparatus. The image forming apparatus has a plurality of detachable process cartridges including image carriers (photosensitive drums) on which latent images are to be formed and developing units which develop the latent images. When a replacement timing for at least one of the process cartridges has arrived, only the developing unit of the process cartridge whose replacement timing has not arrived is driven in accordance with the state of the cartridge whose replacement timing has arrived to perform image forming.

摘要： The invention provides a developer carrying member for carrying a developer for developing an electrostatic image formed on an image bearing member, including an elastic layer, and a surface layer provided on a surface of the developer carrying member and including a resin and particles, wherein the particles have a property of being frictionally charged in a polarity opposite to a normal charging polarity of the developer, and the particles are exposed from the surface in an area rate within a range from 15 to 60% with respect to a surface area of the developer carrying member. In this manner, an uneven heating of the toner image can be suppressed even if the recording material generates an undulation after passing a nip.

摘要： A development device includes a developer container; a rotary cylindrical developer carrier including an outer electrode including multiple electrode portions arranged in a circumferential direction of the developer carrier, an inner electrode provided on an inner circumferential side of the developer carrier from the outer electrode, an insulation layer disposed between the outer electrode and the inner electrode, and a surface layer; and a bias power source to apply a first bias voltage and a second bias voltage to the inner electrode and the outer electrode, respectively. The first bias power source causes an electrical potential difference that changes with time between the inner electrode and the outer electrode to cause the developer to hop on a circumferential surface of the developer carrier. At least one of the first bias voltage and the second bias voltage has a cyclic waveform in which pulse-on time is reduced.
