Abstract:
A pressing rotating member comprising a base layer, an elastic layer and a surface layer, in this order, the surface layer having pores, wherein when placing an observation region of 8 μm long×11 μm wide at a cross section of the surface layer in a thickness direction of the surface layer—a direction perpendicular to a circumferential direction of the pressing rotating member, a degree of orientation f of the pores observed in the observation region is 0.20 or higher, and an orientation angle Φ of the pores observed in the observation region is 0° to 10°.
