摘要： A fixing device includes a support supporting a nip formation assembly that presses against an opposed rotary body via an endless belt to form a fixing nip between the endless belt and the opposed rotary body. The support includes a base contacting the nip formation assembly. An upstream projection projects from the base in a pressurization direction of the opposed rotary body at a position on the base corresponding to or upstream from an upstream edge of the fixing nip in a recording medium conveyance direction. A downstream projection projects from the base in the pressurization direction of the opposed rotary body at a position on the base corresponding to or downstream from a downstream edge of the fixing nip in the recording medium conveyance direction. The downstream projection is spaced apart from the upstream projection in the recording medium conveyance direction.

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： By using a black-image forming device, an abrasive pattern is formed on a sheet conveying belt so that toner is input to a contact section where a cleaning blade is in contact with the sheet conveying belt. After the toner is input to the contact section where the cleaning blade is in contact with the sheet conveying belt and then the sheet conveying belt makes one or more revolutions, a process control is performed in which Y, M, and C tone patterns and B tone pattern are transferred onto the sheet conveying belt.

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.
