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.

摘要： An image forming apparatus includes a fixing device. The fixing device includes a rotatable endless fixing member, a nip forming member arranged inside the fixing member, a pressing member in contact with the nip forming member via the fixing member, and a heating source configured to heat the fixing member. When an abnormality occurs in at least one of the fixing device and other devices included in the image forming apparatus, a rotation of the fixing member is stopped prior to stopping a rotation driving of a discharging unit and, after stopping, the fixing member is controlled to rotate.

摘要： A fixing device includes an endless belt rotatable in a predetermined direction of rotation and a nip formation assembly disposed opposite an inner circumferential surface of the endless belt. An opposed rotary body is pressed against the nip formation assembly via the endless belt to form a fixing nip between the endless belt and the opposed rotary body through which a recording medium bearing a toner image is conveyed. A belt holder contacts and supports each lateral end of the endless belt in an axial direction thereof. The belt holder is isolated from the opposed rotary body with a first interval interposed therebetween in the axial direction of the endless belt.

摘要： A fixing device includes an endless flexible belt, an elongated stationary pad, a rotary pressure member, a low-friction sheet of lubricant-impregnated material, a first adhesive layer, and a second adhesive layer. The endless flexible belt is looped into a generally cylindrical configuration extending in an axial direction thereof for rotation in a rotational, circumferential direction thereof. The elongated stationary pad is stationarily disposed inside the loop of the belt. The rotary pressure member is disposed parallel to the belt. The rotary pressure member presses against the stationary pad via the belt to form a nip therebetween. The low-friction sheet of lubricant-impregnated material covers the stationary pad to supply lubricant between the stationary pad and the belt across the nip. The first adhesive layer is disposed between the low-friction sheet and the stationary pad. The second adhesive layer is disposed between the low-friction sheet and the stationary pad.

摘要： A fixing device includes an endless flexible belt, a stationary pad, a rotary pressure member, and a lubrication mechanism. The endless flexible belt is looped into a generally cylindrical configuration extending in an axial direction thereof for rotation in a rotational, circumferential direction thereof. The stationary pad is stationarily disposed inside the loop of the belt. The rotary pressure member is disposed parallel to the belt. The rotary pressure member presses against the stationary pad via the belt to form a nip therebetween, through which a recording medium is conveyed in a conveyance direction. The lubrication mechanism supplies lubricant between the stationary pad and the belt, and includes a first sheet of lubricant-impregnated material and a second sheet of lubricant-impregnated material.

摘要： A separator includes a front edge disposed opposite an outer circumferential surface of an endless belt. The front edge contacts and separates a recording medium from the endless belt. A separation plate mounts the front edge. A contact plate projects from the separation plate in an axial direction of the endless belt and contacts a belt holder that supports the endless belt. A bracket projects from the separation plate in a direction orthogonal to the direction in which the contact plate projects from the separation plate. The bracket includes a notch that engages the belt holder. The contact plate contacting the belt holder and the notch of the bracket engaging the belt holder produce an interval between the front edge of the separator and the outer circumferential surface of the endless belt.
