Abstract: A transfer unit includes, as transfer rollers, a first roller and a second roller of which the latter has an elastic layer larger in the axial direction than that of the former, a first bearing member, a second bearing member, a roller holder, a first urging member, a second urging member, a switching cam, a transfer voltage power supply, and a driving mechanism. By rotating the roller holder, one of the first and second rollers is arranged opposite an image carrying member and, by rotating the switching cam, the first or second roller arranged opposite the image carrying member is arranged either at a reference position at which, by being kept in pressed contact with the image carrying member, the first or second roller forms a transfer nip or at a released position at which the first or second roller lies away from the image carrying member.

Abstract: A fixing device has a fixing member, a pressing member, a pressing mechanism, a pressure changing mechanism, and a moving mechanism. The fixing member has a fixing belt. The pressing member forms a fixing nip portion by making contact with the fixing member. The pressing mechanism presses the pressing member against the fixing member to apply a nip pressure to the fixing nip portion. The pressure changing mechanism changes the nip pressure. The moving mechanism moves the fixing member in a sheet width direction which is perpendicular to a sheet conveying direction. The pressing mechanism has a holding member rotatably holding the pressing member and held swingably in such directions as to approach and recede from the fixing member. The moving mechanism moves the fixing member in the sheet width direction in coordination with the nip pressure being applied or removed by the pressure changing mechanism.

Abstract: An image forming apparatus includes an image forming portion, an image input portion, a transfer unit, a transfer voltage power supply, and a control portion. The transfer unit includes a transfer roller having a metal shaft and an elastic layer laid around the outer circumferential face of the metal shaft to form a transfer nip by keeping the elastic layer in pressed contact with an image carrying member, and transfers a toner image formed on the image carrying member to a recording medium as it passes through the transfer nip. The transfer unit includes, as the transfer roller, a first roller, and a second roller having a larger axial-size elastic layer compared to the first roller. The control portion arranges first or second roller opposite the image carrying member according to width-direction sizes of the recording medium and the image data fed to the image input portion.

Abstract: A fixing unit fixes the toner image on a sheet by causing the sheet carrying a toner image to pass through a nip portion formed by bringing a rotary fixing member and a rotary pressing member into pressure contact with each other. The image forming apparatus includes an image forming apparatus main body having a fixing unit accommodating portion for accommodating the fixing unit in an insertable and removable manner, and a heating unit provided in the image forming apparatus main body and heating a rotary fixing member of the fixing unit mounted on the fixing unit accommodating portion from outside in a radial direction. The direction in which the fixing unit is inserted into and removed from the fixing unit accommodating portion coincides with the axial direction of the rotary pressing member.

Abstract: A fixing device includes: a fixing element; a heat source heating the fixing element; a press roller pressed against the fixing element, to form with the fixing element a nip region where a recording sheet passes; a driver device rotating the press roller; and a controller controlling the heat source to set a temperature of the fixing element to a predetermined target temperature, and controlling the driver device to set a rotation speed of the press roller to a predetermined target rotation speed. The controller determines the target rotation speed by adding a correction value to a normal rotation speed, based on the temperature of the fixing element at start of job, a type of the recording sheet, ambient temperature, and elapsed time from start of paper feed, and sets the rotation speed of the press roller to the target rotation speed.

Abstract: A damper mechanism has first and second rail members, a biasing member, and a slide member. The first rail member is fixed inside the opening/closing member along the up/down direction, and has an oblong guide hole formed therein extending along the longitudinal direction. The second rail member has fixed to a top end part thereof an engaging pin inserted through the guide hole, and has a bottom end part swingably supported on the apparatus main body. The biasing member biases the first and second rail members in a direction in which these approach each other. The slide member is made of resin fixed to the engaging pin, slides while in contact with the first rail member and the opening/closing member, and prevents contact between the engaging pin and an inner circumferential rim of the guide hole.

Abstract: A sheet feeder includes a sheet feeding cassette stored in a cassette storage part, a heater and flow regulating plates. A first gap is formed between the bottom plate of the sheet feeding cassette and a bottom portion of the cassette storage part, and having an air intake port. A second gap is formed between the side plate of the sheet feeding cassette and a side portion of the cassette storage part and has a vent port communicating with the first gap and the sheet storing part. The flow regulating plates are disposed in the first gap so as to form a duct together with the sheet feeding cassette and the cassette storage part. Air flow is generated such that air is supplied from the air intake port into the first gap, is heated, rises through the second gap from the vent port, and flows to the sheet storing part.
