Patent ID: 7794307

Claim:
A method for correcting a semi-conductive belt, the semi-conductive belt comprising a resin and a conductive substance, the method comprising: supporting the semi-conductive belt such that the belt is supported with a rotatable supporting roll in a state that a tensile force is imparted to the semi-conductive belt; subjecting the geometrically defective part to a heat treatment, wherein the heat treatment is carried out in a state that the supporting roll contacts an inner surface of the belt opposite the geometrically defective part; grinding the heat treated geometrically defective part of the semi-conductive belt to flatten the geometrically defective part wherein the grinding is carried out in a state that the supporting roll contacts an inner surface of the belt opposite the geometrically defective part, wherein grinding is carried out with the belt being in the state of tensile force and wherein the supporting roll is not rotated.
