摘要： A toner container and an image forming apparatus are disclosed. The toner container includes a guiding member formed at a part surrounding a toner outlet to be protruded from a circumferential surface of the toner container for guiding an opening or closing operation of a shutter member in a circumferential direction of the toner container. The image forming apparatus includes an image forming apparatus main body. The image forming apparatus main body includes a main body side shutter for opening or closing a toner supplying opening to be connected to the toner outlet. When the shutter member is opened, an end surface of the guiding member pushes the main body side shutter together with the opening operation of the shutter member, and the toner supplying opening is opened and is connected to the toner outlet.

摘要： A novel development device includes a developer roller, a developer reservoir, a rotatable conveyor, and a replenisher unit. The developer roller is configured to supply toner particles to the electrostatic latent image. The developer reservoir is configured to hold the developer therewithin for application to the developer roller. The rotatable conveyor is configured to rotate within the developer reservoir to convey the developer toward the developer roller. The replenisher unit has a tubular member terminating at a port opening in the developer reservoir. The replenisher unit is configured to direct a particulate material through the tubular member into the developer reservoir via the port. The particulate material is toner particles, carrier particles, or a mixture of toner particles and a given amount of carrier particles. The port is submerged in the developer within the developer reservoir as the rotatable conveyor rotates.

摘要： A method and an apparatus of controlling a charge voltage including the steps of applying, charging, detecting, and determining. The applying step applies an application voltage having a direct-current voltage and an alternating-current voltage superimposed onto the direct-current voltage to a charge-applying member to charge a charge carrier. The changing step charges the alternating-current voltage of the application voltage. The detecting step detects an alternating current flowing through the charge carrier when the charge-applying member applies the application voltage to the charge carrier. The determining step determines a value of the alternating-current voltage of the application voltage based on at least two alternating currents detected by the alternating-current detector.

摘要： A charging member, which can be provided in a process cartridge and/or in an image forming apparatus, includes a conductive supporting member, an electrical resistance control layer formed on an outer circumferential surface of the conductive supporting member, and a nonconductive gap retaining member configured to retain a gap between the conductive supporting member and an image carrying member closely disposed to each other to have a constant distance. At least a portion of the nonconductive gap retaining member is mounted on the electrical resistance control layer at both ends of the conductive supporting member, and a circumference of the nonconductive gap retaining member projects from the electrical resistance control layer. An amount of projection of the gap retaining member from the electrical resistance control layer decreases as the gap retaining member tapers in a direction toward a center of an image formation region.
