PROBLEM TO BE SOLVED: To provide a driving force transmission device and an image forming apparatus that can reduce a space in the depth direction of an apparatus body and suppress blowout of toner clouds.SOLUTION: An image forming apparatus comprises: a frame body that supports therein a plurality of gears transmitting a rotational driving force and includes a plane part extending in a direction intersecting with a direction in which the rotational driving force is transmitted; and an air channel that passes an air taken in from the outside of the frame body to be exhausted to the outside of the frame body. The air channel has a continuous closed cross-sectional shape in which a plurality of air inlets formed on one face of the frame body are connected to one exhaust port formed on the other face of the frame body.SELECTED DRAWING: Figure 4 |
