摘要： An internal cover that covers a unit inside an image forming apparatus is provided. The internal cover includes: a cover portion openable and closable by rotation on a rotation shaft; a hinge portion that forms the rotation shaft of the cover portion, where the rotation shaft is inclined with respect to a vertical direction of the image forming apparatus to allow the cover portion to be opened diagonally upward; and a hand-cranked fixing screw that maintains the cover portion in a closed state. The cover portion is opened diagonally upward as the hand-cranked fixing screw is released, and the cover portion is fixable in an opened state at a predetermined position.

摘要： A toner supplying device includes: a toner container that is tubular, includes a spiral groove at an outer circumferential face, a toner discharge opening at one end in a longitudinal direction, and a depression at the other end in the longitudinal direction, and is rotationally driven to convey toner contained in the toner container along the spiral groove in the longitudinal direction to discharge the toner from the toner discharge opening; a rotational driving unit that engages with the one end of the toner container to rotationally drive the toner container to cause the toner container to discharge the toner; and a projection provided at an interior portion at which the toner container is installed, and having an inclination in which a projection amount increases toward downstream in a rotational direction of the toner container. The projection is formed to fall in the depression of the toner container.

摘要： A heater fixing holder is configured to be detachably attached on a heating roller and a heater inside the heating roller. The heating roller constitutes part of a fixing device configured to fix an image onto a recording medium. The heater fixing holder includes a fitting portion configured to be penetrated with and fit with an end portion of the heater and a gripping portion configured to hold an outer peripheral surface of the heating roller. The heater fixing holder is configured to hold and fix the heater at a position at which the heater does not contact an inner wall of the heating roller.

摘要： A fixing device includes a fixing rotator, a pressure rotator, and a cleaning device. The cleaning device cleans a surface of at least one of the fixing rotator and the pressure rotator. The cleaning device includes a cleaning web, a web holder, a winder, a cleaning pressure rotator, a pressure applier, and a temporary holder. The cleaning web slides over and cleans the at least one of the fixing rotator and the pressure rotator. The web holder holds and sends out the cleaning web. The winder winds the cleaning web. The cleaning pressure rotator presses the cleaning web against the at least one of the fixing rotator and the pressure rotator. The pressure applier presses against the cleaning web along a width direction of the cleaning web perpendicular to a direction in which the cleaning web is wound. The temporary holder temporarily holds the pressure applier.

摘要： A drawing-up magnetic pole and a control magnetic pole of a magnetic field generator that is disposed in a developer carrier are adjacent to each other and a prevention member is provided that secures, between the prevention member and an upper end of a side wall of a developer supply conveyance path, a supply path through which a developer in the developer supply conveyance path passes toward the developer carrier at least over the entire width of a developing area and that prevents a control retained developer, which is prevented by a developer control member from passing through a control gap, from moving toward the surface of the developer carrier along lines of the control magnetic force. The peak of the magnetic flux density of the drawing-up magnetic pole in the normal direction is disposed below the lower end of the supply path.
