An elastic roller includes an inner layer side elastic member around a roller shaft, and a coating layer surrounding around the inner layer side elastic member, the coating layer contacting a belt-shaped member. The coating layer is made of silicone resin having JIS-C hardness of 20 degrees or less. A base layer and an intermediate layer of the inner layer side elastic member have JIS-A hardness of 30 to 80 degrees. The rubber hardness of the base layer is higher than the rubber hardness of the intermediate layer. The intermediate layer has tearing strength of 25 N/mm or more, the tearing strength being measured using an unnicked angle-shaped test piece in accordance with JIS K 6252. The intermediate layer has internal grooves having a groove angle of 40 to 160 degrees and having a V-shaped cross section.

An inventive rubber composition contains a rubber component including EPDM, a peroxide crosslinking agent, a white filler, and not less than 0.1 part by mass of a quaternary ammonium salt based on 100 parts by mass of the rubber component. An inventive molded rubber product (1) is made from the rubber composition. Thus, the novel rubber composition containing the rubber component including the EPDM, the peroxide crosslinking agent and the white filler can be imparted with any desired color (e.g., a light color such as white or a non-black color) and can form a molded rubber product excellent in strain resistance properties and the like without inhibition of the crosslinking of the EPDM. The molded rubber product is produced by using the rubber composition.
