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.

摘要： An image forming apparatus includes a charging bias output device, a developing bias output device, a transfer bias output device, and a controller. The controller controls the transfer bias output device to supply a transfer bias from a time at which a first position of a photosensitive member arrives at a transfer position after the charging bias output device starts supplying a charging bias. An initial value of the transfer bias is controlled to be smaller than a normal set value for a predetermined time period which is a time after the transfer bias starts to be supplied and within a time corresponding to a rise time during which a surface potential of the photosensitive member reaches a predetermined potential after the charging bias starts to be output. The first position of the photosensitive member is a position at which the charging device starts charging the photosensitive member.
