Image forming device having intake duct

An image forming device comprising:

• an image forming unit including:
• a photosensitive member configured to rotate about an axis;
• a developing roller configured to supply toner to the photosensitive member to form a toner image thereon;
• and
• a blade configured to regulate an amount of toner carried by the developing roller;
• a first frame disposed in an upstanding posture and configured to support the image forming unit from one side in a first direction parallel to the axis and partition the image forming unit from atmosphere, an air intake being formed in the first frame to allow air communication between atmosphere and the image forming unit;
• an intake duct elongated in the first direction, the intake duct having an opposing part in opposition to the image forming unit in a second direction perpendicular to the first direction, an opening being formed in the opposing part and air introduced into the intake duct flowing toward the image forming unit through the opening;
• and
• an exposure unit configured to expose the photosensitive member to a laser beam and form an electrostatic latent image on the photosensitive member for forming the toner image, the intake duct being disposed between the exposure unit and the image forming unit in the second direction,
• wherein the second direction is a vertical direction, the intake duct is disposed above the image forming unit and under the exposure unit;
• and
• wherein the opening opposes the blade and air introduced into the intake duct downwardly flows toward the blade through the opening.
