Developing device

Abstract

A developing device that is composed of plural constituent members and that causes a developer to adhere to an image holding body holding an image includes a facing member that is provided to be rotatable and that is disposed at a position facing the image holding body, an opening that is disposed in a state of facing an image holding body side and that is for supply of the developer to the image holding body, a blocking member that partially blocks the opening and that is disposed in a state where a gap is provided between the blocking member and the facing member that is disposed on a side opposite to a side on which the image holding body is installed with the blocking member interposed therebetween, a flow path that extends in an axial direction of the facing member provided to be rotatable, through which air flows in the axial direction, and that reaches the gap at an end portion on a downstream side of a flow of the air in the axial direction, a suction port that is provided at the end portion of the flow path on the downstream side in the axial direction and into which the air in the flow path is sucked in a direction intersecting the axial direction and air in the gap is sucked, and a division portion that partially blocks the suction port and that divides the suction port into an upstream side and a downstream side in the axial direction.
