    摘要: A sheet delivery mechanism designed to discharge successive sheets to different delivery positions includes offset rollers, an offset unit, an offsetting force generator and an offset unit swinging mechanism. The offset rollers is rotatably supported by the offset unit to discharge each sheet in a sheet transport direction. The offsetting force generator produces a driving force for shifting the offset unit back and forth along a direction perpendicular to the sheet transport direction between a reference position and offset positions. The offset unit swinging mechanism swings the offset unit about an axis parallel to rotary shafts of the offset rollers in such a manner that a sheet output direction in which the offset rollers eject each sheet varies to a direction pointing away from a sheet delivery tray when the offset unit is shifted along the direction perpendicular to the sheet transport direction by the offsetting force generator.

    摘要: A fixing device includes a fixing member in contact with an unfixed image constituted of developer T on one side of a recording material P; and a pressure member pressed against the fixing member. The fixing device fixes the unfixed image onto the recording material P by causing the recording material P, charged so as to have a same polarity as a polarity of the developer T, to pass through a gap between the fixing member and the pressure member. In the fixing device, an inflow current into the fixing member Ih is 0 when the recording material P passes through the gap between the fixing member and the pressure member. This securely restrains the developer on the recording material from electrostatically offset to the side of the fixing device, thereby maintaining the formation of high quality images.

    摘要: A fixing unit includes a heat roller and a pressing roller that comes in pressure contact with the heat roller, and passes the recording paper with an unfixed toner image formed thereon through the nip between the heat roller and pressing roller to thereby fix the toner image to the recording paper by applying heat and pressure thereto. A cleaning device for removing the toner remaining on the heat roller or pressing roller in the fixing unit includes cleaning rollers made of metal arranged in press-contact with the heat roller and pressing roller, the peripheral surface of the cleaning rollers being formed with projected and indented shapes to thereby remove the leftover toner appropriately.
