Abstract:
A rubber composition capable of forming a foam such as a roller main body which has a low rubber hardness and is soft in a state in which an average cell diameter thereof is small is provided. The rubber composition includes NBR whose Mooney viscosity is 15 to 50 having a proportion being 10 parts by mass or more in 100 parts by mass of the total amount of rubber, epichlorohydrin rubber whose Mooney viscosity is 5 to 35 having a proportion being 10 parts by mass or more in 100 parts by mass of the total amount of rubber, and 10 parts by mass or less of carbon black and 7 parts by mass or less of a foaming agent with respect to 100 parts by mass of the total amount of rubber, and has a Mooney viscosity of 35 or less.
