PURPOSE: To provide a roll small in the change of electric resistance even when utilizing environments are changed and in the dispersion of electric resistance by using a polyurethane elastic body for a resistant layer of the roll and using together an alkali metal salt and an electroconductive particle except the alkali metal salt with the polyurethane elastic body.

CONSTITUTION: An electrifying roll is made, for instance, by forming a polyurethane elastic body layer 12 on the surface of a core shaft 11. On the surface of the polyurethane elastic layer 12, a resin coating film may be formed or a surface treating liquid may be applied. The polyurethane elastic body is constituted of the well-known made of polyol and polyisocyanate. As the polyol, polyester polyol or ether polyol is exemplified. A condensed polyester polyol obtained by condensing a dicarboxylic acid such as adipic acid and a polyol such as ethylene glycohol, a lactone based polyester polyol or the like is mentioned as the polyester polyol.
