摘要： An electrically conductive roll includes a shaft body and at least a conductive elastic layer formed by extrusion on an outer circumferential surface of the shaft body. The conductive elastic layer is formed from at least one conductive rubber composition which includes a rubber material, a thermoplastic resin having crosslinkable double bonds and a melting point in a range from 40° C. to 100° C., and at least one conductive agent. The thermoplastic resin is included in an amount of 5 to 50 wt. % of a total amount of the rubber material and the thermoplastic resin.

摘要： A method of producing an electrically conductive roll having a proper crown shape at lower costs through a smaller number of process steps and without polishing. In this production method, a crown-shaped rubber layer is formed unitarily on a metal core by variably controlling the amount of a rubber material adhering on the metal core along the length of the metal core during extrusion of the rubber material.

摘要： A developing roll which may reduce stress imparted on toner and have uniform transportability of toner. The developing roll comprises a shaft, an elastic layer provided on an outer peripheral surface of the shaft, and a cylindrical outermost layer provided directly or indirectly via a layer on an outer peripheral surface of the elastic layer, wherein an outer peripheral surface of the outermost layer is formed into a rough surface by distribution of multiple dimples in such a manner that open ends thereof do not overlap one another on the surface and a portion other than the dimples on the rough surface forms a remaining portion of a cylindrical shape.
