Patent ID: 8750757

Claim:
An image forming apparatus configured to form an image on a recording sheet, comprising: a chassis having an opening, the opening being formed on a first side of the chassis; a drawer configured to hold a plurality of photosensitive members therein in line and to be slidably installed in the chassis through the opening and movable between a first position and a second position in the chassis, the plurality of photosensitive members being configured to carry toner images; an intermediate transfer belt unit including an endless belt, the endless belt having a surface which faces the plurality of photosensitive members and being configured to have the toner images on the plurality of photosensitive members transferred onto the surface in cooperation with a plurality of primary-transfer members; a secondary-transfer roller, which is arranged on a second side opposite from the first side within the chassis and configured to transfer the toner images on the surface of the endless belt onto the recording sheet; a first feed roller, which is arranged in a vicinity of the second side and configured to convey the recording sheet toward the secondary-transfer roller; a cleaner device, which is arranged in a position between one of the plurality of photosensitive members being in a most upstream position along the predetermined rolling direction of the endless belt and the secondary transfer roller, and configured to collect residual toner from the surface of the endless belt and convey the collected residual toner toward an outer side of the endless belt along a widthwise direction, the cleaner device including an auger and a blade, the auger and the blade being in horizontally overlapping positions at least partially in a same vertical level with the drawer; a waste toner container, which is configured to be removably installed in the chassis and to store the residual toner collected by the cleaner device; a connector, which is arranged on the outer side of the endless belt along the widthwise direction and is connected to the cleaner device, and to which the waste toner container is detachably attached, to convey the residual toner collected by the cleaner device to the waste toner container; a first feeding path, which is formed to extend in a range between the first feed roller and the secondary transfer roller; a second feeding path, which is formed in a clearance between the endless belt and the waste toner container to convey a recording sheet being inserted through a sheet inlet toward the first feed roller, the sheet inlet being formed on the first side of the chassis and to merge into the first feeding path in a vicinity of the first feed roller; and a second feed roller, which is arranged in a horizontally overlapping position at least partially with the endless belt and configured to convey the recording sheet toward the first feeding path through the second feeding path.
