<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a conductive elastic body, the method exhibiting excellent production efficiency while using thermosetting polyurethane, and to provide an easily producible roller for an electrophotographic device. <P>SOLUTION: A method for manufacturing a conductive elastic body comprises: preparing a dispersion liquid by dispersing a conducting agent in thermosetting polyurethane; and curing the dispersion liquid to form a conductive elastic body. Carbon black having a pH of 7.5 or more, a DBP absorption amount of 50 ml/100 g or less and a volatile content of 1.1 mass% or less, and resin-coated carbon black are used as the conducting agent. <P>COPYRIGHT: (C)2013,JPO&INPIT |
