There is provided a charging member (1) capable of improving adhesion of an elastic layer (3) with a surface layer (4), which is used for an electrophotographic image forming device. The charging member (1) has a shaft body (2) having conductivity, the elastic layer (3) having conductivity which is formed along the outer circumference of the shaft body (2), and the surface layer (4) formed along the outer circumference of the elastic layer (3). The elastic layer (3) contains a rubber and a calcium carbonate having a spindle shape. The surface layer (4) is composed of a cured material of a composition containing a matrix polymer, a polyisocyanate having two or more isocyanate groups in a molecule, and a porous particle. The calcium carbonate in the elastic layer (3) exists more at a side closer to the surface layer (4) than at a side closer to the shaft body (2). |
