A sheet conveying apparatus to convey a sheet to an image forming unit includes a main body, an opening/closing member, and first, second, and third portions. The opening/closing member can be opened and closed with respect to the main body, and the first, second, and third portions pivotably support the opening/closing member. The second support portion is provided below the first support portion and above the third support portion. Each of the first, second, and third portions include a projecting portion and a hole portion. A difference between a greatest length of the third projecting portion and a diameter of the third hole portion is larger than a difference between a greatest length of the first projecting portion and a diameter of the first hole portion and is larger than a difference between a greatest length of the second projecting portion and a diameter of the second hole portion.

An image forming apparatus includes a chassis having an opening, a cover, photosensitive members, an intermediate transfer belt, a primary-transfer member, a secondary-transfer roller, a cleaner device, an external-sheet inlet, a waste toner container, a connector, and a conveying roller, which is arranged within the feeding path to feed the recording sheet inserted through the external-sheet inlet in the feeding path. The conveying roller is mounted on the waste toner container and removable from the chassis along with the waste toner container.
