    Abstract: A paper feed roller including an elastic layer composed of thermosetting polyurethane containing a plasticizer, wherein an amount of the plasticizer is within a range of 10 to 50 pts. mass based on 100 pts. mass of the thermosetting polyurethane, and a surface residual charge on the elastic layer is within a range of 90 to 170 V. The surface residual charge is a value determined by single-point measurement of a surface potential of the elastic layer. The measurement includes rotating the paper feed roller in a circumferential direction, electrifying the surface of the elastic layer with a corotron while rotating the paper feed roller, and measuring the surface potential at a center point on the paper feed roller in a roller axis direction in a position where the paper feed roller is rotated by 90 degrees from a position where the surface of the elastic layer is electrified.

    Abstract: Provided is a cleaning blade to be used for removing a residual toner that remains on a surface of a counterpart member in an electrophotographic image forming device, by sliding contact with the counterpart member. The cleaning blade includes a conductive support including a plate-shaped portion; a blade part that is formed on the plate-shaped portion and is made of a polyurethane rubber; and a conductive adhesion layer that is provided between the plate-shaped portion and the blade part and contains a conductive agent. In the cleaning blade, the blade part contains a potassium salt in an amount of 0.3 mass % or more and less than 10 mass %, and the potassium salt includes at least one kind of anion selected from the group consisting of CF3SO2C4F9SO2N−, (CF3SO2)2N−, (FSO2)N−, C28H28BO6−, AlCl4−, Al2Cl7−, NO3−, BF4−, PF6−, CF3COO−, CF3SO3−, (CF3SO2)3C−, AsF6−, SbF6×, F(HF)N−, CF3CF2CF2CF2SO3−, (CF3CF2SO2)2N−, CF3CF2CF2COO−, (C4F9SO2)2N−, CF2(CF2SO2)2N− and CF3SO2NH2−.

    Abstract: The present disclosure provides a cleaning blade (2) that prevents toner from slipping through the cleaning blade in a long time use. The cleaning blade (2) is used to remove residual toner remaining on a surface of a counterpart member (1) in an electrophotographic image forming device by sliding contact with the counterpart member (1). The cleaning blade (2) includes a support (3) including a plate-shaped portion (31); and a blade part (4) made of polyurethane, and joined to the plate-shaped portion (31) in integral forming. The blade part (4) includes a plate-shaped blade body portion (41) that is joined to a plate surface of the plate-shaped portion (31), and a reinforcing portion (42) that extends from a surface of the blade body portion (41) and is joined to a front end face of the plate-shaped portion (31). The reinforcing portion (42) has a curved surface (421) that curves inward.
