1. A developing roller which comprises a shaft having good electroconductivity and an electroconductive elastic layer formed on the outside periphery of said shaft, supports a developer on its surface to form thin films thereof and in this state, rotates in contact with or in close vicinity to the surface of a latent image preserving body that preserves an electrostatic image on its surface, and thus supplies the developer to the surface of the latent image preserving body so as to visualize an electrostatic image on the surface of the latent image preserving body, said electroconductive elastic layer having a thermal conductivity of at least 0.15 W/m·
