<P>PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of minimization by efficiently arranging a driving motor as a driving source of an image forming means, a plurality of gears which are connected with the driving motor and transmit a rotative driving force to the image forming means, a circuit substrate unit of performing an electric control of the image forming means, a fan unit which replaces air in a main body case with the outside air and the like. <P>SOLUTION: A first frame 61a which is formed substantially in a rectangular shape is disposed in a main body case and a fan unit 69, a circuit substrate unit 64 and a driving gear unit 63 are located on the same outer surface of the first frame 61a. Further, a circuit substrate unit 64 is disposed in a superposed state on the outside of the driving gear unit 63 and is disposed so that the outer edge of the circuit substrate unit 64 becomes nearly equal to the outer edge of the fan unit 69 in the superposition direction. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
