Abstract:
1. An image forming apparatus comprising: a main body; a plurality of developing units separably installed at the main body, each of the plural developing units developing an electrostatic latent image into a visible image through developer; and a transfer unit to transfer the developer of each developing unit developed into the visible image to a printing medium, wherein each of the plural developing units comprises a photosensitive body on which the electrostatic latent image is formed, and a developing unit housing at which the photosensitive body is rotatably mounted; the transfer unit comprises an intermediate transfer belt to which developer on the photosensitive body is transferred, first transfer rollers, each of the first transfer rollers transferring the developer from the photosensitive body to the intermediate transfer belt, a transfer unit frame at which the first transfer rollers are movably mounted, and a second transfer roller to transfer developer from the intermediate transfer belt to the printing medium; and the developing unit housing comprises position regulating guides, each of the position regulating guides, when each developing unit is installed at the main body, supporting a shaft of each first transfer roller so that the intermediate transfer belt comes into contact with the photosensitive body at a uniform angle.
