Abstract: Provided are: a conductive roller in which detachment and scraping of particles from a surface layer are unlikely to occur; and a method of producing the same. A conductive roller 10 includes: a shaft 1; and an elastic layer 2 and a surface layer 3, which are sequentially formed on the outer circumference of the shaft 1. In this conductive roller 10, the surface layer 3 is composed of a mixture of a surface layer resin composition and particles, the surface layer resin composition contains a heat-curable or energy ray-curable urethane resin, and the particles are composed of a particle resin composition containing a urethane (meth)acrylate.
