1. A rotary member including an inner circumference and an outer circumference rotatable along a circumferential direction of the inner circumference and the outer circumference, the rotary member comprising:
carbon fibers wound in the circumferential direction;
a matrix resin in which the carbon fibers are embedded;
a structure which includes a plurality of carbon nanotubes having a bent shape with a bent portion, forms a network structure including a contact portion where the carbon nanotubes are in direct contact with each other, and is provided on surfaces of the carbon fibers; and
a first sizing agent which functions as an aqueous cross-linking agent, the first sizing agent cross-links and fixes the carbon nanotubes which are in direct contact with each other around the contact portion,
wherein, in the structure, a gap surrounded by the plurality of carbon nanotubes is formed, and the first sizing agent does not fill up the gap.
