Abstract: An image forming apparatus includes an apparatus main body that includes an image formation unit forming an image on a recording material, a fixation unit that includes a fixing unit fixing the image formed by the image formation unit onto the recording material and that is attachable to and detachable from the apparatus main body, a first duct that is attached to the fixation unit to face the fixing unit and through which a gas that cools the fixing unit flows, and a second duct that is attached to the apparatus main body to be adjacent to the first duct and through which a gas that cools the fixing unit flows.

Abstract: A powder conveying device includes a first conveying component through which gas containing powder is to be conveyed; a second conveying component to which a downstream end of the first conveying component is connected and through which the gas received from the first conveying component is to be conveyed, the second conveying component extending in a second gas conveying direction that intersects a first gas conveying direction defined by the first conveying component; a third conveying component extending from the second conveying component and through which the gas received from the second conveying component is to be conveyed, the third conveying component extending in a third gas conveying direction that intersects the second gas conveying direction; a fourth conveying component to which a downstream end of the third conveying component is connected and through which the gas received from the third conveying component is to be conveyed, the fourth conveying component extending in a fourth gas conveying d

Abstract: A developing device includes: a container that contains developer; a developer holder that rotates with the developer being held on a surface thereof to transport the developer to a developing region; and a cooling unit. An introduction port is provided at a position corresponding to the developing region, the introduction port allowing suction of a floating substance generated in the developing region in a transverse direction of the container. The cooling unit is connected to the introduction port to allow passage of gas containing the floating substance in a longitudinal direction of the container, and cools the container with the gas. An intake port is connected to an end of the cooling unit in the longitudinal direction, the intake port allowing introduction of gas.

Abstract: An image forming apparatus, for forming an image with a fixing unit that fixes a toner image to a recording material and with a first transport path, includes: a first guide unit that guides one side of a recording material discharged from the fixing unit and transported through the first transport path; a second guide unit that guides the other side of the recording material transported thorough the first transport path; a blowing part through which gas is sent to the one side of the recording material transported through the first transport path; and a gas guiding part that faces the second guide unit with the first transport path interposed between the gas guiding part and the second guide unit and that guides, in a direction away from the first transport path, gas that is sent from the blowing part and whose traveling direction is changed by a recording material.

Abstract: An image forming apparatus includes: an image forming section that forms, with a developer containing toner, a toner image on a recording material; a fixing unit that fixes a toner image formed at the image forming section to a recording material; a recovery unit that recovers waste powder containing toner discharged from the image forming section; and a gas circulation unit in which gas for cooling the vicinity of the image forming section or the vicinity of the fixing unit circulates and that has a portion disposed between the recovery unit and the fixing unit.

Abstract: A filter includes a collecting member that has a pleat and collects particles while allowing wind to pass through, and a holding member that holds the pleat at an end in an elongated direction in which the pleat is elongated. The holding member has a wind-passing portion through which wind flowing along the pleat is allowed to pass.

Abstract: A drying device includes a light irradiation part that irradiates a recording medium on a recording-medium movement route with light to evaporate moisture contained in droplets attached to the recording medium, and an air blowing part that is positioned on a downstream side from the light irradiation part in a recording-medium movement direction, and blows air onto the recording medium on the recording-medium movement route. The drying device changes the distance between a light irradiation position of the light irradiation part on the recording-medium movement route and an air-blowing target position of the air blowing part on the recording-medium movement route.

Abstract: A drying unit includes: an irradiation portion that radiates laser light to a recording medium being fed in a predetermined feeding direction, so as to evaporate moisture of liquid droplets adhering to the recording medium; a supply portion that blows and supplies air to a space between the irradiation portion and the recording medium through and outlet from a position at a downstream side of the irradiation portion in the feeding direction; an absorption portion that absorbs at least a part of the air flowing to an upstream side in the feeding direction along the recording medium in a position at an upstream side of the irradiation portion in the feeding direction; and a suction guide unit as defined herein.
