Abstract: There is disclosed a member for office machines which comprises a core body and an annular elastic body installed on the peripheral surface thereof, wherein the expansion rate of the annular elastic body E(%) falls within the range of 5 to 30%, when expressed by the formula E(%)={(d1−d2)/d2}×100 wherein d1 in mm is the diameter of the core body, or a longest value in the cross-section of the core body in the shape of a roller or odd-shape; and d2 in mm is the inside diameter in mm of the annular elastic body before being installed on the peripheral surface of the core body. The member for office machines enables stable and steady paper sheet feeding, when used as a paper feeding member in electrophotographic equipment and electrostatic recording equipment, and equipment having a variety of paper feeding mechanisms such as ink-jet printers, automatic teller machines (ATM), money exchange machines, counting machines, automatic vending machines and cash dispensers (CD).
