Abstract: A developing apparatus includes: a supply path configured to supply a developer; a discharge path configured to discharge the developer supplied from the supply path and perform developing; a developer holding portion configured to exert a predetermined force for holding the developer at the discharge path; and a developer accommodation portion accommodating the developer which is supplied from the supply path, and having a space volume so that the developer does not spout out from the discharge path on which the predetermined force is exerted by the developer holding portion according to an increase in an internal pressure of the developer accommodation portion when the developer is supplied from the supply path in a state where a predetermined amount of the developer is accommodated.

Abstract: A developer conveying apparatus for conveying a developer that develops an electrostatic latent image includes a rotation unit which rotates around rotation shaft pallalel to a developer conveying direction, a first developer conveying portion which is provided in the rotation unit and which conveys the developer in an axial direction of the rotation shaft, and a second developer conveying portion which is provided in the rotation unit at a position where a distance from the rotation shaft is different from that of the first developer conveying portion, and which conveys the developer in a direction opposite to that of the first developer conveying portion.

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.
