Inking Roller Patents (Class D18/58)
  • Patent number: 8663748
    Abstract: In the formation of a conductive roller 1, a compound forming an elastomer by curing through an electron beam irradiation or a ultraviolet ray irradiation is applied onto an outside of a shaft member 2 to form an elastomeric coating layer 3R and then the elastomeric coating layer is cured through an irradiation of an electron beam or a ultraviolet ray to form an elastic layer, whereby the elastic layer can be formed cheaply without sacrificing precision of peripheral dimension to largely reduce the cost of the conductive roller.
