Image forming apparatus

An image forming apparatus to form an image on a recording sheet, comprising:

• a chassis having a first opening, the first opening being formed on a first side of the chassis;
• a plurality of photosensitive members, which are set in the chassis and carry toner images;
• an intermediate transfer belt, which is an endless belt to roll in a predetermined direction, has a surface including a first plane and a second plane, and has the toner images on the plurality of photosensitive members transferred on to 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 transfers the toner images on the surface of the intermediate transfer belt onto the recording sheet;
• a first feed roller, which is arranged in a vicinity of the second side and conveys 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 intermediate transfer belt and the secondary-transfer roller, to collect residual toner from the surface of the intermediate transfer belt;
• a waste toner container, which is movable in the chassis to be removably installed in the chassis through the first opening and settled in a position opposite from the plurality of photosensitive members across the intermediate transfer belt, to store the residual toner collected by the cleaner device;
• a connector, which 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 extends in a range between the first feed roller and the secondary-transfer roller;
• a second feeding path, which is a path for a recording sheet being inserted through a sheet inlet, the sheet inlet being formed on the first side of the chassis, and merges into the first feeding path in the vicinity of the first feed roller;
• and
• a second feed roller, which is arranged in a position closer to the first side of the chassis with respect to the waste toner container within the second feeding path and in an overlapping position to at least partially overlap with the waste toner container when viewed along a horizontal plane,
• wherein the first plane of the intermediate transfer belt has a first end and a second end and extends horizontally to face the plurality of photosensitive members;
• wherein the second plane of the intermediate transfer belt has a first end and a second end, the first end extending from the first end of the first plane downwardly in an inclined angle with respect to the first plane;
• wherein the waste toner container is movable along the second plane of the intermediate transfer belt and settled to face the second plane of the intermediate transfer belt;
• and
• wherein the second feed roller is arranged in a position out of a course of the waste toner container being installed in and removed from the chassis.
