An image forming apparatus has an image forming body which is rotatable in a subsidiary scanning direction. A plurality of imagewise exposure devices for imagewise exposing the image forming body are arranged to face the image forming body and to be aligned in a straight line in a primary scanning direction perpendicular to the subsidiary scanning direction of the image forming body. A common supporting member is provided for supporting the plurality of exposure devices, and bearing members are provided on first and second ends of the common supporting member. The plurality of exposure devices are: (i) radially arranged on the common supporting member with respect to a rotation axis of the image forming body, and (ii) fixed on the supporting member with respect to the bearing members, and the image forming body is rotatable against the common supporting member through the bearing members.
