    摘要： A method for manufacturing a developing agent carrier of a hollow or solid cylindrical shape having an outer peripheral surface and an irregularity section formed on the outer peripheral surface to carry a developing agent is provided. The method comprises a step of preparing a base material of a hollow or solid cylindrical shape which is to become the developing agent carrier, the base material having an outer peripheral surface; and a step of forming the irregularity section by pressing dice for formation of the irregularity section against the outer peripheral surface of the base material. The irregularity section forming step comprises a first step of forming a plurality of first depression portions on the outer peripheral surface of the base material by use of a die and a second step of forming a plurality of second depression portions on the outer peripheral surface of the base material by use of a die identical with or different from the die used in forming the first depression portions, in such a manner that the second depression portions are dislocated from the first depression portions.
