    摘要： A powder container for an image forming apparatus includes: a rotatable powder storage storing powder; an opening on one end of the powder storage, through which a nozzle can be inserted; and a scooping portion to scoop up powder on an opening side, and supply the powder to a powder receiving hole of the nozzle when the powder storage rotates. The scooping portion includes a scooping surface extending inwardly from an inner wall surface of the powder storage and an inner end portion extending in a rotation axis direction of the powder storage, with an edge approximately parallel to the rotation axis. In a cross-section perpendicular to the rotation axis, the scooping surface is inclined toward an upstream side in a rotation direction of the powder storage with respect to a virtual line that passes through the rotation axis and is tangent to the edge of the inner end portion.

    摘要： A toner container (32) includes a rotatable container body (33). The container body includes an opening portion (33c) and a plurality of projections (33a). The opening portion is on a first end, which is opposite a second end, of the container body in a rotation axis direction. The plurality of projections are each protrude inward and have a slope inclined with respect to the rotation axis direction. The plurality of projections are disposed such that, out of two adjacent projections in the rotation axis direction, one projection closer to the first end of the container body in the rotation axis direction overlaps the other projection closer to the second end of the container body in the rotation axis direction, in an area of the one projection closer to the second end and an area of the other projection closer to the first end in the rotation axis direction.

    摘要： A toner container includes a container body, a gear, a held portion, an information storage device, a holding portion, and a connecting portion. The container body is rotatable around a rotation axis. The gear is disposed on a leading end of the toner container in the attaching direction of the toner container. The held portion is disposed such that the gear is exposed on the leading end in the attaching direction. The information storage device communicates with the body of the image forming apparatus. The holding portion is held by the held portion via the connecting portion. The information storage device, the holding portion, and the connecting portion are disposed at oblique positions excluding positions on a horizontal line and a vertical line. The connecting portion covers a part of the gear in a rotation direction and includes a rib-shaped portion that connects the held portion and the holding portion.

    摘要： A toner container includes a cylindrical container body having a head with an opening in the head, a cap into which the head of the container body is inserted, and a sheet member attached inside the cap. The cylindrical container body rotates around a rotation axis extending in a longitudinal direction of the container body to transport toner contained in the container body toward the opening. The cap has a toner outlet through which the toner discharged from the opening is discharged outside the toner container. The sheet member includes a first elastic-deformation portion that is elastically deformable and located near the toner outlet, and a second elastic-deformation portion that is elastically deformable and located in the container body and near the opening.
