Image forming apparatus with a movable sheet guide in a feeding path

摘要

An image forming apparatus is provided. The image forming apparatus includes a chassis, a cover, photosensitive members, an intermediate transfer belt, primary-transfer members, a secondary-transfer roller, a first feed roller, a cleaner device, a waste toner container, which is movable along the predetermined direction to be removably installed in the chassis through a first opening and stores residual toner, a connector, a first feeding path, a second feeding path being a path for a recording sheet inserted through a sheet inlet and includes a sheet guide to guide the recording sheet, and a second feed roller. The second feed roller is movable along with at least a part of the sheet guide. The waste toner container is movable through space, which is occupied by the second feed roller in an upper position, and the first opening when the second feed roller is in a lower position.

主权项

1. 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 rolling in a predetermined rolling direction and 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 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 arranged in a vicinity of the second side and configured to convey the recording sheet toward the secondary-transfer roller; a cleaner device 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 second 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; a waste toner container configured to be removably installed in the chassis and to store the residual toner collected by the cleaner device; a connector connected to the cleaner device, and to which the waste toner container is detachably attached, the connector being configured to convey the residual toner collected by the cleaner device to the waste toner container; a first feeding path configured to extend in a range between the first feed roller and the secondary-transfer roller; a second feeding path configured to extend from the first side toward the second side and configured to guide the recording sheet from the first side to the first feed roller, the second feeding path including a sheet guide to guide the recording sheet; and a separator pad arranged on the sheet guide, wherein the sheet guide is movable between an upper position closer to the connector and a lower position farther from the connector.
