Abstract:
A toner carrier which supports a toner on its surface to form thin films thereof and in this state, supplies the toner to the surface of an image formation body in contact with or in close vicinity to said image formation body so as to form visible image thereon, said toner carrier having at least 0.70 of Z value, which is represented by the formula (1) obtained from deformation restoration behavior of the surface of said toner carrier at the time of measuring the universal hardness of the surface thereof:Z=We/(We+Wr)â€ƒâ€ƒ(1) wherein We is elastic energy from among the energies in relation to the deformation of the surface thereof, said elastic energy being obtained from deformation restoration behavior of the surface of said toner carrier at the time of measuring the universal hardness of the surface thereof; and Wr is plastic energy therefrom, and wherein the Asker C hardness on the surface thereof is 50 to 80 degrees.
