    Abstract: An object of the present invention is to provide a charging roller in which detachment of particles from a surface layer as well as abrasion and scraping of the particles, which are caused by contact and the like with other member such as a photoreceptor during the use, are unlikely to occur. The charging roller 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. The surface layer 3 is composed of a mixture of a surface layer resin composition and particles, the surface layer resin composition has a tensile elongation at break of 51% or greater, and the particles have a reaction force of 1.0 to 10.3 mN under 1-μm compression.
