DEVELOPING APPARATUS

摘要

A developing apparatus including a first chamber; a second chamber forming a circulation path for the developer; a rotatable shaft in the first chamber; a first blade provided on the rotation shaft to feed the developer in a predetermined direction in the first chamber; a second blade provided on the rotation shaft to feed the developer fed by the first blade in a direction opposite the predetermined direction; a discharging portion provided downstream of the second blade to discharge the developer in the first chamber; and a regulating member having a regulating surface continuously extending in a rotational moving direction of the rotation shaft, the regulating member being provided on the rotation shaft in a region between the first blade and the second blade, a region connecting with a downstream end of the first blade, or a connecting with a downstream end of the second blade.

主权项

1. A developing apparatus comprising:
a first chamber in which a developer including toner and carrier is fed; a second chamber in fluid communication with said first chamber to form a circulation path for the developer; a rotation shaft rotatable in said first chamber; a first blade member provided on said rotation shaft and configured to feed the developer in a predetermined direction in said first chamber; a second blade member provided on said rotation shaft and configured to feed the developer fed by said first blade member in a direction opposite the predetermined direction; a discharging portion provided downstream of said second blade member with respect to the predetermined direction and configured to discharge the developer in said first chamber; and a regulating member having a regulating surface continuously extending in a rotational moving direction of said rotation shaft and configured to regulate the developer fed by said first blade member, said regulating member being provided on said rotation shaft in a region between said first blade member and said second blade member, a region connecting with a downstream end of said first blade member, or a connecting with a downstream end of said second blade member.
