An image forming apparatus having a uniform nip between a photosensitive body and a transfer body. The image forming apparatus has a photosensitive unit on which an electrostatic latent image is formed, a developer feed unit to feed a developer onto the electrostatic latent image to form a visible image, and a transfer unit. The transfer unit has a curved side of a semi-hollow tubular shape that contacts the photosensitive unit, and a planar side opposite the curved side and secured at a support member, to transfer the visible image formed on the photosensitive unit to a recording medium. The curved side of the transfer unit has a uniform radius of curvature in an axial direction. Accordingly, the image forming apparatus can not only maintain a constant nip in relation to electrical resistance and contact pressure, but can also adjust the electrical resistance of the transfer unit by appropriately setting factors such as volume resistivity of the conductive elastic member.
