2. Description of the Related Art At present, in electrophotographic devices such as copying machines and printers, first, the surface of the photoconductor is uniformly charged by a charging means such as a charging roller, and the charge on the photoconductor is neutralized by an optical method. To form an electrostatic latent image, then a toner image is formed on the electrostatic latent image by a developing roller or the like, which is transferred to a recording medium such as paper by a transfer belt or the like, and further by a fixing roller or the like. A method of obtaining a recorded image by heating and fixing the transferred image on a recording medium is adopted.

A variety of performances are required for the transfer member for electrophotographic apparatus. In recent years, the performance required by providing a multilayer structure having an inner layer and an outer layer and providing different functions to each layer is satisfied. The method of function separation, which is designed as follows, is the mainstream.

In order to improve the cleaning property of the toner, it is considered to lower the dynamic friction coefficient of the surface of the transfer member for electrophotographic apparatus. As a method for lowering the dynamic friction coefficient, it is common to increase the hardness and tensile stress of the material. However, if the material is too hard, it loses its flexibility, and it cannot respond to the bending of the member, and the outer layer is destroyed,
Can not follow the deformation of the base layer, causing wrinkles on the surface,
There arises a problem that the outer layer is peeled off from the base layer.

As a method for lowering the dynamic friction coefficient, a method of blending a matting agent has been proposed. This is to reduce the kinetic friction coefficient by adding a matting agent to appropriately roughen the surface and reduce the contact area of the friction portion. However, this method has a problem in that the smoothness of the surface is impaired, and if the surface roughness is too large, the toner particles are buried and the cleaning property of the toner is rather deteriorated.
