PROBLEM TO BE SOLVED: To provide a method for manufacturing a conductive rubber roller reduced in the longitudinal irregularity of electric resistance by injecting a liquid silicone rubber material in a mold to cure the same. SOLUTION: In the manufacturing method of the conductive rubber, a pulse control means is used in the injection of a material and controlled so that the injection pressure of the material becomes an arbitrary set value or below at the point of time when the whole injection amount of the material reaches 85-98%.
