Abstract
An image forming apparatus includes a body having a port, an image forming section positioned further than the center of the body toward a first side while including an image forming unit that forms an image on a medium by a developer including an additive and a fixing unit that heats and fixes the image onto the medium, a duct extending from the vicinity of the fixing unit to a position further than the center of the body toward a second side, a connecting portion connected to a portion of the duct, which is farthest from the fixing unit, and the port on the second side while being wider than the duct such that a flow velocity of a gas inside the connecting portion is less than that inside the duct, and a moving unit that moves the gas from the fixing unit to the connecting portion through the duct.
Claims17
An image forming apparatus comprising:
- an apparatus body in which a discharge port is formed;
- an image forming section that is positioned further than the center of the apparatus body in a width direction toward a first side and that includes
- a developer-image forming unit configured to form a developer image on a recording medium by using a developer including an additive and
- a fixing unit configured to fix the developer image onto the recording medium by heating the developer;
- a duct that extends, in the apparatus body, in a longitudinal direction from a vicinity of the fixing unit to a position further than the center of the apparatus body in the width direction toward a second side;
- a connecting portion that is connected, on the second side in the apparatus body, to a portion of the duct, which is opposite to a portion of the duct that faces the fixing unit, and the discharge port and that is formed so as to be wider than the duct in such a manner that a flow velocity of a gas that flows inside the connecting portion is less than a flow velocity of a gas that flows inside the duct;
- and
- a moving unit that causes a gas to move from the fixing unit to the connecting portion by passing through the inside of the duct,
- wherein an entire width of the connecting portion in a horizontal direction perpendicular to the longitudinal direction is larger than an entire width of the duct in the horizontal direction.

- a connecting portion that is connected, on the second side in the apparatus body, to a portion of the duct, which is opposite to a portion of the duct that faces the fixing unit, and the discharge port and whose cross-sectional area in a plane that is perpendicular to the longitudinal direction is larger than a cross-sectional area of the duct in the plane;
- and
- a moving unit that causes a gas to move from the fixing unit to the connecting portion by passing through the inside of the duct,
- wherein an entire width of the connecting portion in a horizontal direction perpendicular to the longitudinal direction is larger than an entire width of the duct in the horizontal direction.
