CROSSLINKED RUBBER ARTICLE FOR PAPER FEEDING ROLL, RUBBER COMPOSITION FOR PAPER FEEDING ROLL, PAPER FEEDING ROLL, IMAGE FORMING DEVICE, AND PAPER FEEDING DEVICE

摘要

PROBLEM TO BE SOLVED: To enhance abrasion resistance while improving a friction coefficient required for a paper feeding roll and keeping performance of that, and to keep stable paper feeding characteristics for a long term.;SOLUTION: The crosslinked rubber article for the paper feeding roll includes at least a polymer and reinforcing filler. The polymer has ethylene-propylene-diene copolymer as a main ingredient, and composed by vulcanizing with sulfur. The crosslinked rubber article for the paper feeding roll is 4.4 to 10 MPa in dynamic elastic modulus (E1, 30°C), and not more than 0.063 in loss tangent (tanδ, 30°C).;COPYRIGHT: (C)2004,JPO&NCIPI
