Imaging system with control member for conveyance path and developing roller having a peeling pole

A developing device, comprising:

• a housing including a developing chamber;
• a developing roller located in the developing chamber to carry a developer in a rotational direction of the developing roller, wherein the developing roller is spaced apart from the housing, wherein the developing roller includes a developing region to transfer the developer to an image carrier, and a peeling pole to which residual developer carried on the developing roller is discharged;
• a conveyance path extending between the developing roller and the housing to accommodate an air flow including the developer from the developing region to the peeling pole in the rotational direction of the developing roller;
• and
• a control member located in the conveyance path in proximity to the peeling pole of the developing roller to reduce a flow rate of the air flow in the conveyance path,
• wherein the control member is biased toward the developing roller to apply a constant pressure against the developing roller, and
• wherein the control member includes a sheet member having a first edge that is attached to the housing, a second edge opposite the first edge, and a magnetic body that is attached to the second edge of the sheet member.

• a control member located in the conveyance path in proximity to the peeling pole of the developing roller to reduce a flow rate of the air flow in the conveyance path, wherein the control member extends in a longitudinal direction parallel to a rotational axis of the developing roller, and wherein the control member includes:
• inflow suppression regions to inhibit the air from flowing, and;
• inflow regions to channel the air to flow therethrough, wherein the inflow suppression regions and the inflow regions are positioned alternately along the longitudinal direction of the control member.
