Patent ID: 7672627

Claim:
An image forming apparatus comprising: an intermediate transfer body that is a belt-shaped member stretched among plural rolls, and that is arranged in an inclined state to a horizontal direction so that a lower traveling course of the belt-shaped member becomes lower toward the downstream side along the traveling direction thereof and becomes higher toward the upstream side thereof; a plurality of image forming portions that are arranged below the intermediate transfer body, and that are arranged in parallel so as to primarily transfer toner images of different colors formed on image carriers onto the lower traveling course of the intermediate transfer body; a secondary transfer unit that is arranged at an end portion on the lower side of the intermediate transfer body arranged in the inclined state to the horizontal direction, and that secondarily transfers, on a recording medium, the toner images primarily transferred onto the intermediate transfer body; a recording medium accommodating container that is arranged below the plural image forming portions in a state of accommodating the recording medium therein, and that feeds the recording medium to the second transfer unit from the downside in the vertical direction toward the upside; a waste toner accommodating container that is arranged so that at least a part thereof is located below the image forming portion located at the end portion of the intermediate transfer body on the side opposite to the side where the secondary transfer unit is arranged, and that accommodates waste toner removed from the image carrier of each image forming portion and waste toner removed from the intermediate transfer body; a first electrical part that is arranged in space above the waste toner accommodating container; and a second electrical part that is arranged in space having a triangular section formed by an upper surface of the recording medium accommodating container, lower surfaces of the plural image forming portions, and a side surface of the waste toner accommodating container.
