PROBLEM TO BE SOLVED: To provide an image forming apparatus in which a nip formed between a photoreceptor and a transfer body is uniform. SOLUTION: The image forming apparatus has a photosensitive part 101 on which an electrostatic latent image is formed; a developer feed power 103 which forms a visible image by feeding developer to the formed electrostatic latent image; and a transfer part 105 of a semi-hollow tubular shape a curved portion of which is in the contact with the photoreceptive part 101, a flat portion of which is fixed by a support member 107, and which transfers a visible image, formed on the photoreceptive part 101, to a recording medium. Herein, the curved portion of the transfer part 105 is structured in a layer of conductive plate material and is formed uniform in curvature along the length of the semi- hollow tube shape. Thus, not only electric resistance and contact pressure-related nip 110 can be kept constant but also electric resistance of the transfer part 105 can be adjusted by appropriately setting the volume resistivity, etc., of the conductive plate material.
