DEVELOPING ROLLER
A developing roller in which the decay rate of the surface potential is high and in which an image failure caused by the accumulation of electric charge does not occur is provided. The developing roller 10 includes a shaft 1, an elastic layer 2 supported on the outer periphery of the shaft, and at l...

| description | A developing roller in which the decay rate of the surface potential is high and in which an image failure caused by the accumulation of electric charge does not occur is provided. The developing roller 10 includes a shaft 1, an elastic layer 2 supported on the outer periphery of the shaft, and at least one coating layer 3, 4 formed on the outer periphery of the elastic layer. The volume resistivity of a layer on the inner periphery side of the elastic layer and the coating layer is smaller than the volume resistivity of a layer on the outer periphery side, and the difference between the volume resistivities of the elastic layer and the coating layer positioned on the outermost periphery side is in the range of 2.8 to 4.3 (Log©cm). |
