Abstract
A developer conveying apparatus for conveying a developer that develops an electrostatic latent image includes a rotation unit which rotates around a rotation shaft extending in an axial direction and parallel to a developer conveying direction, a first developer conveying portion which is provided in the rotation unit and which has an opening configured to convey the developer in a first axial direction of the rotation shaft, and a second developer conveying portion which is provided in the rotation unit and which has an opening configured to convey the developer in a second axial direction opposite to the first axial direction. A distance from the rotation shaft to the opening in the first developer conveying portion is different than a distance from the rotation shaft to the opening in the second developer conveying portion.
