## Abstract

A container member includes a container body that contains a recording medium and that tilts with respect to a horizontal direction such that a leading edge of the contained recording medium is higher than a trailing edge, a trailing edge restriction portion that comes into contact with the trailing edge of the recording medium that is contained in the container body in a front-rear direction of the recording medium and that restricts a position of the trailing edge of the recording medium, and a restriction portion that restricts movement of the trailing edge in a thickness direction of the recording medium that is contained in the container body.

## Claims

### Claim 1

A container member comprising:
a container body that contains a recording medium and that tilts with respect to a horizontal direction such that a leading edge of the contained recording medium is higher than a trailing edge;
a trailing edge restriction portion that comes into contact with the trailing edge of the recording medium that is contained in the container body in a front-rear direction of the recording medium and that restricts a position of the trailing edge of the recording medium, wherein the trailing edge restriction portion is movable and configured to move in a predetermined range in the front-rear direction; and
a restriction portion that restricts movement of the trailing edge in a thickness direction of the recording medium that is contained in the container body and comprises a projecting portion projected from the entire upper edge portion of the trailing edge restriction portion to restrict a center of the trailing edge in a width direction of the recording medium.

### Claim 2 (depends on 1)

The container member according to claim 1,
wherein the restriction portion comes into contact with the trailing edge in the thickness direction and restricts movement of the trailing edge.

### Claim 3 (depends on 2)

The container member according to claim 2,
wherein the restriction portion comes into contact with a portion of the trailing edge that comes into contact with the trailing edge restriction portion.

### Claim 4

A container member comprising:
a container body that contains a recording medium and that tilts with respect to a horizontal direction such that a leading edge of the contained recording medium is higher than a trailing edge;
a trailing edge restriction portion that includes a facing portion that faces the trailing edge of the recording medium that is contained in the container body in a front-rear direction of the recording medium, that comes into contact with the trailing edge in the front-rear direction, and that restricts a position of the trailing edge of the recording medium, wherein the trailing edge restriction portion is movable and configured to move in a predetermined range in the front-rear direction; and
a projecting portion that is included in the trailing edge restriction portion and that projects from an upper edge portion of the facing portion forward in the front-rear direction, wherein the projecting portion projects from the entire upper edge portion of the facing portion in a width direction of the recording medium, so that the projecting portion contacts a center of the trailing edge of the recording medium in a width direction.

### Claim 5 (depends on 4)

The container member according to claim 4,
wherein the projecting portion projects in the front-rear direction.

### Claim 6 (depends on 1)

An image forming apparatus comprising:
the container member according to claim 1;
a transport unit that transports the recording medium that is contained in the container member; and
an image forming unit that forms an image on the recording medium that is transported by the transport unit.

### Claim 7 (depends on 2)

An image forming apparatus comprising:
the container member according to claim 2;
a transport unit that transports the recording medium that is contained in the container member; and
an image forming unit that forms an image on the recording medium that is transported by the transport unit.

### Claim 8 (depends on 3)

An image forming apparatus comprising:
the container member according to claim 3;
a transport unit that transports the recording medium that is contained in the container member; and
an image forming unit that forms an image on the recording medium that is transported by the transport unit.

### Claim 9 (depends on 4)

An image forming apparatus comprising:
the container member according to claim 4;
a transport unit that transports the recording medium that is contained in the container member; and
an image forming unit that forms an image on the recording medium that is transported by the transport unit.

### Claim 10 (depends on 5)

An image forming apparatus comprising:
the container member according to claim 5;
a transport unit that transports the recording medium that is contained in the container member; and
an image forming unit that forms an image on the recording medium that is transported by the transport unit.

### Claim 11 (depends on 1)

An image forming apparatus comprising:
the container member according to claim 1;
a transport unit that transports the recording medium that is contained in the container member; and
an image forming unit that forms an image on the recording medium that is transported by the transport unit.

### Claim 12

A container member comprising:
containing means for containing a recording medium, the containing means tilting with respect to a horizontal direction such that a leading edge of the contained recording medium is higher than a trailing edge;
means for coming into contact with the trailing edge of the recording medium that is contained in the containing means in a front-rear direction of the recording medium and configured to move in a predetermined range in the front-rear direction for restricting a position of the trailing edge of the recording medium; and
means for restricting movement of the trailing edge in a thickness direction of the recording medium that is contained in the containing means, and comprises a projecting portion projected from the entire upper edge portion of the trailing edge restriction portion for restricting a center of the trailing edge in a width direction of the recording medium.
