Abstract

An image forming apparatus includes a cassette provided drawably into/out of an apparatus body and storing recording media, a waste toner container being provided drawably into/out of the apparatus body along a pull-out direction of the cassette, a cover member movable between a close position where an opening portion enabling the waste toner container to be drawable into/pulled out of the apparatus body is closed and an open position where the opening portion is opened, and a moving portion. The moving portion engages with the cover member located at the open position and moves the cover member from the open position to the close position along with an insertion of the cassette into the apparatus body.

First claim

What is claimed is:

1. An image forming apparatus, comprising:
a cassette provided drawably into/out of an apparatus body and storing a recording medium;
an image forming portion forming an image on the recording medium conveyed from the cassette;
a waste toner container recovering toner discharged out of the image forming portion, the waste toner container being provided drawably into/out of the apparatus body along a pull-out direction of the cassette;
a cover member movable between a close position where an opening portion enabling the waste toner container to be drawable into/pulled out of the apparatus body is closed and an open position where the opening portion is opened; and
a moving portion engaging with the cover member located at the open position and moving the cover member from the open position to the close position along with an insertion of the cassette into the apparatus body.

2. The image forming apparatus according to claim 1 , wherein the cover member is provided turnably on the apparatus body and at least one of the moving portion or the cover member is provided with a guide portion turning the cover member along with the insertion of the cassette into the apparatus body.

3. The image forming apparatus according to claim 1 , wherein the cover member is provided turnably centering on a turning shaft provided in a direction intersecting with a direction in which the waste toner container is inserted/pulled out.

4. The image forming apparatus according to claim 3 , wherein the cassette is juxtaposed horizontally with a storage portion for the waste toner container and turning shaft is disposed in a horizontal direction.

5. The image forming apparatus according to claim 4 , wherein the cassette includes a projecting portion projecting to a cover member side so as to obstruct the waste toner container from being pulled out of the apparatus body in a state in which the cassette is inserted into the apparatus body, and
wherein the moving portion is provided in the projection portion.

6. The image forming apparatus according to claim 1 , further comprising a hold portion holding the cover member at the close position in a state in which the cassette is pulled out of the apparatus body.
