    摘要: An image forming apparatus includes: a paper conveying portion for conveying a paper; an image forming portion for forming a visible toner image on the paper being conveyed, with a toner in accordance with input image information; and a fixing unit for fusing and fixing an unfixed toner image formed on the paper to the paper by using a heat roller and a pressing roller, and is constructed such that the pressing roller is composed of a metal core that forms a core shaft of the pressing roller and an elastic part that covers an outer periphery of the metal core, and a heat capacity at a center portion of the pressing roller with respect to a direction perpendicular to a paper's direction of conveyance is smaller than heat capacities at both ends of the pressing roller.

    摘要: A front access type image forming apparatus includes an image scanning section located at an upper part of a housing of the apparatus for obtaining image information from an original, a sheet feeding section located at a lower part of the housing, and an image forming section disposed between the image scanning section and the sheet feeding section at one side of the housing. The image scanning section, the image forming section and the sheet feeding section together form a generally U shape in frontal cross section, a sheet delivery portion being formed between the image scanning section and the sheet feeding section. The length of a sheet delivery tray as measured along a sheet transport direction is made smaller than the length of a maximum printable sheet size so that large-sized printed sheets discharged onto the sheet delivery tray stick out from one side of the apparatus.

    摘要: A sheet stacking device includes: an evacuation section for transporting and ejecting sheets; a sheet exit tray for stacking the ejected sheets; an arm supporting member; and a sheet presser arm including a supported end at one end, a free end at the other end which is capable of pressing the sheets stacked on the sheet exit tray directly or via a contact member attached to the free end, and a flexure portion having flexibility between the supported end and the free end. The supported end is attached to the arm supporting member. The arm can apply, by the flexibility of the flexure portion, a pressing force to the sheets stacked on the sheet exit tray and a repulsive force to each of the ejected sheets when a front end of the ejected sheet strikes against the arm.
