Abstract: To provide a peeling member capable of suppressing a waving phenomenon of a peeling sheet, contacting linearly with a roller sufficiently, preventing deformation due to jamming of a paper and showing excellent paper peeling performance, and to provide a peeling device provided with the peeling member. The peeling member includes a peeling sheet 10 that peels a paper from a fixing roller 6 of an electronic photographic device. The peeling sheet 10 is formed of one metal plate, the peeling sheet 10 including a peeling portion 2 that forms the distal end portion, and a support portion 3 that is thicker than the peeling portion 2. The peeling portion 2 is arranged at one long side of the metal plate such that a paper passing surface 2b of the peeling portion 2 is formed as a flat surface continued to a surface of the support portion 3.

Abstract: To provide a non-oil-impregnated sliding bearing having superior low friction capable of suppressing an increase of a shaft temperature in a continuous use, and a bearing apparatus and an image forming apparatus provided with the sliding bearing. Sliding bearings 5a to 5c support rotation shafts on cylinder inner surface in a rotatable manner. Each of the sliding bearings 5a to 5c is formed of a molded member of a non-oil-impregnated resin composition that does not contain oil. The resin composition contains an injection-moldable ultrahigh molecular weight polyethylene resin as a base resin, a polytetrafluoroethylene resin as an additive, and an acicular inorganic filler having Mohs hardness of 3 or less. The resin composition contains 65 vol % or more of the ultrahigh molecular weight polyethylene resin, 5-25 vol % of the polytetrafluoroethylene resin, and 1-20 vol % of the acicular inorganic filler, based on the whole of the resin composition.

Abstract: A drawer pull-out guide includes a carcass rail to be fixed to a furniture carcass, an extension rail displaceable relative to the carcass rail between a closed position and an open position, and a rolling body and a supporting body movable along a running limb of the carcass rail and a running surface of the extension rail upon a movement of the extension rail. A clearance is formed on the running limb of the carcass rail and/or on the running surface of the extension rail. The rolling body is accommodated within the clearance in the closed position of the extension rail and is thereby relieved from the load of the extension rail. In the closed position of the extension rail, the load of the extension rail is carried by the rolling body. The rolling body and the supporting body are arranged in a common running carriage.
