## Abstract

In one embodiment, a toner container comprises a toner container body in which toner is stored, a cover portion configured to cover the toner container body, and a projection. The projection is provided in the vicinity of a rear end portion in a longitudinal direction of the cover portion or a longitudinal direction of the toner container body, and projecting toward a rear side of the toner container.

## Claims

### Claim 1

A toner container comprising:
a toner container body in which toner is stored;
a toner discharge port for discharging the toner;
a cover portion configured to cover the toner container body;
a projection at one in a longitudinal direction of the cover portion; and
a first rib and a second rib extending in the longitudinal direction on a left side and a right side, in a width direction, of the cover portion, respectively,
the cover portion comprising:
a first inclined surface extending in the longitudinal direction and inclined from the first rib to a vicinity of a center of the top surface in the width direction, and
a second inclined surface extending in the longitudinal direction and inclined from the first rib to a vicinity of a center of the top surface in the width direction, the first inclined surface and the second inclined surface projecting outward from the first rib and the second rib,
the toner discharge port being parallel to the first inclined surface.

### Claim 2 (depends on 1)

The toner container according to claim 1, wherein the first inclined surface and the second inclined surface are inclined at different angles.

### Claim 3 (depends on 1)

The toner container according to claim 1, wherein the first inclined surface and the second inclined surface are smooth planes.

### Claim 4 (depends on 1)

The toner container according to claim 1, wherein a concave portion is formed on a side surface of the toner container body provided on the side of the second inclined surface.

### Claim 5 (depends on 4)

The toner container according to claim 4, wherein a cutout portion is formed at a position of the concave portion.

### Claim 6 (depends on 5)

The toner container according to claim 5, wherein the cutout portion of the top surface is parallel to a plane in which the first and second ribs are disposed.

### Claim 7

An image forming device in which a toner container can be inserted in a predetermined direction, the toner container comprising:
a toner container body in which toner is stored;
a toner discharge port for discharging the toner;
a cover portion configured to cover the toner container body;
a projection at one in a longitudinal direction of the cover portion; and
a first rib and a second rib extending in the longitudinal direction on a left side and a right side, in a width direction, of the cover portion, respectively,
the cover portion comprising:
a first inclined surface extending in the longitudinal direction and inclined from the first rib to a vicinity of a center of the top surface in the width direction, and
a second inclined surface extending in the longitudinal direction and inclined from the first rib to a vicinity of a center of the top surface in the width direction, the first inclined surface and the second inclined surface projecting outward from the first rib and the second rib,
the toner discharge port being parallel to the first inclined surface.

### Claim 8 (depends on 7)
