An image forming apparatus includes an image forming portion, a waste toner housing container, an open/close member, and an air blowing unit. The image forming portion forms an image. The waste toner housing container is disposed on one side surface of the image forming portion to house a waste toner discharged from the image forming portion. The open/close member opens and closes an opening portion provided in a side surface of an apparatus body to mount and remove the waste toner housing container. The air blowing unit is provided close to the waste toner housing container on a side surface of the apparatus body that is adjacent to a side surface on which the open/close member is installed. The air blowing unit feeds air to the image forming portion from a side of the waste toner housing container toward an opposite side.
