An image forming apparatus includes a photosensitive drum, a developing device, a toner container, a cleaner, a waste toner container, and a waste toner conveying pipe. The cleaner is configured to clean a peripheral surface of the photosensitive drum after a toner image has been transferred to the printing medium. The waste toner container is configured to accommodate therein waste toner removed from the peripheral surface of the photosensitive drum by the cleaner. The waste toner conveying pipe is configured to convey the waste toner from the cleaner to the waste toner container. The cleaner is located between the photosensitive drum and the fixing device in a vertical direction. The developing device is located below the photosensitive drum. The waste toner container is located below the cleaner. The toner container covers at least a part of an upper surface of the waste toner container.

A process unit includes a photosensitive drum rotatable about a rotational axis extending in a first direction. A development unit includes a development roller configured to supply toner to the photosensitive drum. A scanner unit is configured to expose the photosensitive drum. A reception portion is configured to receive toner from a toner container for supplying toner into the development unit. The scanner unit and the photosensitive drum overlap each other as viewed from a second direction perpendicular to the first direction and a gravitational direction. The scanner unit is arranged at a center in the first direction in an apparatus main body.
