1. A fixing rotating member comprising:
a cylindrical base member comprising at least a resin;
an electro-conductive layer on the base member; and
a resinous layer on a surface of the electro-conductive layer, the surface being opposed to a surface facing the base member,
the electro-conductive layer extending in a circumferential direction of an outer circumferential surface of the base member,
the electro-conductive layer comprising silver,
the electro-conductive layer having a volume resistivity of 1.0×10−8 to 8.0×10−8 Ω·m, and
the electroconductive layer having a compressive elastic modulus of 8 to 30 GPa, the compressive elastic modulus being measured by contacting an indenter with a first surface of the electroconductive layer opposite to a surface facing the base member, and the compressive elastic modulus being an average value of compressive elastic moduli of a thickness region of 0.1 to 0.2 μm from the first surface of the electroconductive layer.
