PROBLEM TO BE SOLVED: To provide a contact charger which prevents a body to be charged from being charged ununiformly also decreases wear of the body to be charged, and also to provide an image forming apparatus which avoids an image quality defect, as in the form of a white streak, and ununiform image quality. SOLUTION: The contact charger which comes into contact with a moving body 5 to be charged and charges the body 5 comprises: a charging member 10 in the form of a cylinder or endless belt, which has a pressure-sensitive, anisotropic and conductive layer which decreases in electric resistance with pressure and an anisotropic conductive layer overlaied further outside than the pressure-sensitive anisotropic and conductive layer and made anisotropic in the direction of its thickness; a conductive roll 11 which stretches the charging member 10 and brings the charging member into contact with the conductive roll 11; and a stretch roll 12 which stretches the charging member 10 upward at an angle in the direction of the movement of the body 5.
