Abstract: A paper conveyance device comprises: a conveyance member having a conveyance surface for conveying a recording medium, the conveyance member extending in a first direction along a front-rear direction of the image forming apparatus that has an opening member for exposing inside of the apparatus, and including a handle disposed on an exposure surface of the opening member, and a swing pivot point that is used to swing the conveyance member around the first direction to expose the conveyance surface when the handle is operated in the open state. The handle is disposed in at least one position in a range between positions near a center of the conveyance member in the first direction. The positions are a certain distance away from the center of the conveyance member along the first direction.

Abstract: In an image reading apparatus, the linear coefficients of expansion of conveyance drive rollers and a linear coefficient of expansion of the holding unit are determined such that the amount of change in the outer diameter of each of the conveyance drive rollers due to a change in temperature environment is substantially the same as the amount of change in the interval between the first reading unit and the second reading unit due to a change in the temperature environment. The conveyance drive rollers are attached to a rotary shaft such that the positions of head portions of screws are alternately located along the axis direction of the rotary shaft on opposite sides of the outer circumference surface in a direction perpendicular to the axis direction of the rotary shaft.

Abstract: An image forming apparatus includes a sheet feeding section for feeding a sheet, and a sheet transportation path defining a transportation path for the sheet fed by the sheet feeding section. An image formation section may be provided so as to form an image. The image formation section may include a photo-conductive member arranged in the sheet transportation path. A fixing section may be provided so as to fix a toner image transferred onto the sheet from the photo-conductive member with heating and pressure rollers. A sheet type recognition device may be provided so as to set information related to a sheet type that is selected by an operator. A sheet linear velocity control device may also be provided so as to change a sheet linear velocity of the feeding section in accordance with the sheet type in order to create relaxation of the sheet.
