摘要： An image forming apparatus includes an image forming section, a fixing device, and circuitry. The image forming section forms an image on a recording medium. The fixing device includes a rotator including a flexible endless belt, a pressure rotator pressed against the rotator to form a nip between the rotator and the pressure rotator, a heater heating the rotator, and a movable shield. The movable shield is disposed between the heater and the rotator to shield the rotator from radiant heat generated from the heater and is movable according to a size of the recording medium. The circuitry is configured to control the image forming section to form the image on the recording medium based on an image forming condition and change at least one of an operating temperature of the movable shield or a shielding amount of the movable shield based on the image forming condition.

摘要： A fixing device includes a heater, a fixing rotator, a pressure rotator to press against the fixing rotator to form a fixing nip between the fixing rotator and the pressure rotator, through which a recording medium is conveyed, a moving device to move the pressure rotator in directions in which the pressure rotator comes into contact with and separates from the fixing rotator, a thermal expansion amount predictor to predict an amount of thermal expansion of the fixing rotator while the recording medium is conveyed, and a nip width adjuster to control a moving distance of the pressure rotator moved by the moving device toward the fixing rotator, depending on the amount of thermal expansion of the fixing rotator predicted by the thermal expansion amount predictor, so as to adjust a width of the fixing nip to maintain a substantially constant width of the fixing nip.

摘要： An optical sensor includes a light-emitting unit to emit light onto a measuring object, a regular reflection light receiver to receive regular reflection light from the measuring object out of the light emitted by the light-emitting unit, and a diffuse reflection light receiver to receive diffuse reflection light from the measuring object out of the light emitted by the light-emitting unit. An angle of incidence of the light emitted onto a surface of the measuring object is not smaller than 75° and not larger than 85°. The diffuse reflection light receiver receives, out of the diffuse reflection light from the measuring object, diffuse reflection light having an angle of reflection with respect to a perpendicular to the surface of the measuring object larger than 0° and smaller than an angle of reflection of the regular reflection light with respect to the perpendicular to the surface of the measuring object.

摘要： An image forming apparatus having a transfer assist mechanism is disclosed. The transfer assist mechanism includes a first blade holder having a first blade, second blade holders having corresponding second blades, and a first slide engaging member and a second slide engaging member which engage the first and second blade holders. When the first slide engaging member and the second slide engaging member are moved corresponding to the width of a continuous recording medium, the first blade holder and some of the second blade holders are selected corresponding to the width of the continuous recording medium, and the first blade and some of the second blades corresponding to the selected some of the second blade holders press the continuous recording medium.
