Abstract:
An object of the present invention is to provide a liquid developing electrographic device roller suppressed in volumetric variation caused by a carrier. As a means for solving the problems, the present invention provides a liquid developing electrophotographic device roller including a shaft and an elastic material layer provided around the outer peripheral side of the shaft, wherein the elastic material layer is formed by using a polyurethane obtained by reacting a polyester polyol with a difunctional isocyanate.
