摘要：An image forming device includes a process cartridge, a wall section, and a flow restrictor. The process cartridge includes a photosensitive drum, a charger, and a frame. The charger is disposed spaced away from the photosensitive drum for charging the photosensitive drum. The frame is formed with a first opening at a position opposite to the photosensitive drum with respect to the charger. The frame is also formed with a first vent hole for ventilation of a space defined by the frame. The first vent hole is positioned upstream of the first opening and downstream of the image transfer position of the photosensitive drum in the rotational direction of the photosensitive drum. The wall section is positioned in direct confrontation with the first opening. The flow restrictor restricts air flow and is provided between the frame and the wall section.
