1. A toner container that is detachably attached to a main body of an image forming apparatus such that a longitudinal direction of the toner container is parallel to a horizontal direction, the toner container comprising:
a cylindrical container body that has an opening on one end thereof in the longitudinal direction, and is configured to convey toner contained therein toward the opening; a cap portion into which the opening of the container body is inserted, and which includes a toner outlet at a bottom portion thereof for discharging toner, which has been discharged from the opening of the container body, to the outside of the toner container in a vertically downward direction; and a shutter member that is held on the bottom portion of the cap portion, and moves along an outer periphery of the cap portion to thereby open and close the toner outlet, wherein the cap portion is formed by integral molding, the cap portion includes
a plurality of claw members that engages with the container body to rotatably hold the container body; anda plurality of mold-processing holes arranged near the respective claw members for forming the claw members, each of the claw members and the mold-processing holes does not overlap the toner outlet formed on the cap portion when the cap portion alone is viewed in a projection plane perpendicular to the longitudinal direction, the container body includes a spiral-shaped projection on an inner circumferential surface thereof, and is held so as to rotate relative to the cap portion, a ring-shaped seal member, for sealing a gap between the cap portion and the container body, is attached to a portion of the cap portion so as to be provided at an opposed position to a circumference of the opening of the container body, and the cap portion includes a recess formed on an attachment surface, to which the seal member is attached, the recess being used when the seal member is to be separated from the cap portion.
