Provided are a rubber composition capable of imparting a high tensile strength to a roller main body so as to be able to be used for equipment that allows paper to pass through at high speed, while maintaining high abrasion resistance of the roller main body and a favorable paper feeding performance of the paper feeding roller; and a paper feeding roller. There is provided a rubber composition contains: a rubber that includes a non-oil extended EPDM having an ethylene content of 55 to 72%; and more than 20 parts by mass and 30 parts by mass or less of a filler, and 2.5 parts by mass or more of a peroxide crosslinking agent per 100 parts by mass of the rubber, in which the filler contains 15 to 30 parts by mass of an amorphous silica per 100 parts by mass of the rubber.
A rubber composition for forming a roller main body of a paper feeding roller, the rubber composition containing:
