An image forming device includes: an image forming unit; an enclosure; and an intake duct. The image forming unit includes a photosensitive member having an axis. The enclosure is configured to house the image forming unit and includes a first wall provided on one side of the image forming unit with respect to a first direction parallel to the axis. An air intake is formed in the first wall to allow air communication between an interior and an exterior of the enclosure. The intake duct is elongated in the first direction. Air drawn in through the air intake flows into the intake duct. The intake duct includes an opposing part. The opposing part opposes the image forming unit in a second direction perpendicular to the first direction. An opening is formed in the opposing part. Air introduced into the intake duct flows toward the image forming unit through the opening.

A developer container for an image forming apparatus includes a housing configured to store developer, a developer conveying member disposed inside the housing and configured to rotate to convey the developer stored in the housing. The developer conveying member includes a rotary shaft, a rotary base member and a sheet-like main body. The main body has a base end portion fixed to the rotary base member and a free end portion configured to be pressed into contact with an inner wall of the housing. The rotary base member includes an urging member configured to urge the main body from an upstream side toward a downstream side in a direction of rotation thereof.

An image forming apparatus includes a plurality of process cartridges and a pair of frames. Each of the plurality of process cartridges includes a photosensitive drum, a charger and a charger supporting wall. One of the pair of frames has a plurality of first openings such that air outside the pair of frames is sucked between the pair of frames through the first openings. The other of the pair of frames has a plurality of second openings such that air between the pair of frames is discharged outside the pair of frames through the second openings. The first openings are positioned on an opposite side of the charger supporting wall from the photosensitive drum. The second openings are positioned on the same side of the charger supporting wall as the photosensitive drum.
