| description | Provided is an electrophotography device development roll in which an increase in the electric charge of a toner is suppressed. This electrophotography device development roll 10 is provided with a shaft 12, an elastic layer 14 formed on the outer circumference of the shaft 12, and a surface layer 16 formed on the outer circumference of the elastic layer 14. The surface layer 16 contains (a) to (c) below. (a) A binder comprising acrylonitrile-butadiene rubber having an acrylonitrile amount of 30 mass% or more; (b) an ion-conducting agent comprising at least one selected from a phosphonium saltand a pyridinium salt; and (c) an electric charge regulator comprising an acrylic polymer having a silicone group or fluorine-containing group and a cationic group.
