<p>An image forming apparatus has four color image forming and transferring portions (42-1, 42-2, 42-3, 42-4) and four image writing heads (43-1, 43-2, 43-3, 43-4) supported by a cover (49) to be rotatably movable upwardly and downwardly. Each case (79) of the portions is so shaped that it does not interfere with the rotational movement of the heads, and has the same shape. Particularly, two opposite side surfaces (79a, 79b) of the case is so shaped that it does not project into the movement locuses (45-1, 45-2, 45-3, 45-4) of the heads not to collide them.</p> |
