Developing roll for electrophotographic machine

A developing roll for use in an electrophotographic machine, the roll comprising:

• a shaft;
• an elastomeric layer that surrounds an outer periphery of the shaft;
• and
• a surface layer that surrounds an outer surface of the elastomeric layer, wherein the surface layer contains a composition that contains:
• an (A) ingredient that comprises a binder resin having a functional group that is reactive with an alkoxy silyl group contained in the following (B) ingredient;
• and
• a (B) ingredient that comprises an ion conductive agent that contains a cation having a chemical structure represented by the following general formula (1):
• R1-N+—R2-Si(OR3)3 (1),
• where:
• R1 is any one of a cyclic organic group, and a linear organic group;
• R2 is a group containing at least (CH2)n, wherein n represents an integer number;
• and
• R3 is an alkyl group,
• wherein the cation in the (B) ingredient is bound with the (A) ingredient, and
• wherein the content of the (B) ingredient is 0.10 to 3 parts by mass with respect to 100 parts by mass of the (A) ingredient.
