Abstract
An object of this disclosure is to reduce differences in the drawn amount of the parison around the mouth of the toner container, thereby reducing the amount of resin for the toner container and the weight thereof. A powder container includes a cylindrical container body to rotate in a horizontal posture, a cylindrical mouth at a first end of the container body, smaller in diameter than the container body, a conveyor to convey the powder inside the container body toward the mouth, a scooping portion deeper in the container body than the mouth, to lift the powder above a powder inlet of a conveying tube inserted from the mouth and drop the powder to the powder inlet, and a radially inner face continuous with an inner end of the scooping portion, extending in a direction crossing the scooping portion and disposed inward in the radial direction than an outermost face of the container body. The radially inner face extends from the mouth toward a second end of the container body and is not inner in the radial direction than an inner rim of the mouth.
