PURPOSE:To reduce the number of manufacturing process so as to reduce a cost at the time of manufacture of a conductive roller having a conductive film made of a plurality of layers. CONSTITUTION:In manufacturing method of a conductive roller provided with a shaft 1, a conductive base layer 2 provided on the outer circumference of the shaft 1, and a conductive film 3 provided on the outer circumference of the conductive base layer 2, the conductive film 3 made of a plurality of layers is pushed out simultaneously, and formed as a shrink tube, and then it is cut in a prescribed length. And the outer circumference of the conductive base layer 2 is covered with the conductive film 3, and heat treatment is carried out so as to form the conductive film 3. |
