<P>PROBLEM TO BE SOLVED: To provide a method for producing a foamed rubber roller which can suppress the occurrence of ammonia causing a defective image when used in the member of an electrophotographic device or an electrostatic recording device. <P>SOLUTION: In the production of the foamed rubber roller, a carvone amide foaming agent and a urea-containing foaming auxiliary are used in a raw material rubber composition. The foamed rubber roller obtained by foaming/vulcanizing the rubber composition formed on the periphery of a core bar is exposed to water, heated, and dried. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
