A first ventilation duct line has a first portion having a first sectional area, a second portion having a second sectional area larger than the first sectional area, and a third portion having an inclined inner face connecting the first portion and the second portion to each other. Further, there is a second ventilation duct line having an opening portion positioned on an inner side of the first portion of the first ventilation duct line.

Ventilation duct line assembly and apparatus

A housing includes a housing main body that has an opening in one surface; a first cover that is openably and closably supported by the housing main body by means of a first rotation portion, that covers at least a portion of the opening, and that is provided with an operation portion that causes the first cover in a closed state to enter an open state, the first rotation portion being provided on a portion of the one surface that is on one side with respect to the opening in one direction; and a second cover that is openably and closably supported by the first cover and of which an operation portion that causes the second cover in a closed state to enter an open state is provided at a position that is separated from the operation portion of the first cover by at least half a distance between the operation portion of the first cover and the first rotation portion in the one direction while being on the first rotation portion side.

Housing and image forming apparatus

A noise reducing structure includes a first resonance tube that extends in a first direction, that takes in from a sound absorbing opening portion a sound wave that is generated from a noise source, and that causes the sound wave to resonate to reduce leakage to outside; and a second resonance tube that extends in a second direction differing from the first direction, and that, along with the first resonance tube, causes the sound wave that is generated from the noise source to resonate to reduce the leakage to the outside.

Noise reducing structure and image forming apparatus

A noise reducing structure includes an internal structural body that includes a noise source; an exterior body that includes an inner side surface facing the internal structural body and that covers an outer side of the internal structural body; a space portion that is surrounded by an erected wall, the internal structural body, and the inner side surface, the erected wall being erected so as to, from one of the internal structural body and the inner side surface towards the other of the internal structural body and the inner side surface, be connected to the other of the internal structural body and the inner side surface; and a sound absorbing opening portion that is connected to the space portion and that is formed at a portion near the noise source.

An image forming apparatus includes: a fixing unit that fixes an unfixed image held by a recording medium by heating the recording medium; a first air discharge unit that is disposed at one end in a direction that cross a recording medium feeding direction of the fixing unit and discharges air around the fixing unit to an outside; a second air discharge unit that is disposed on a downstream side of the fixing unit in the recording medium feeding direction and discharges air around the second air discharge unit to an outside; and an air discharge duct member that causes discharge air of the first air discharge unit and discharge air of the second air, discharge unit to merge together and guides resulting merged air to a discharge opening of a rear wall of an apparatus main body of the image forming apparatus.

Image forming apparatus including an air discharge duct

An image forming apparatus includes an exposure unit that forms a latent image by irradiating a photoconductor body with light by using light emitting elements that are arranged along an axial direction of the photoconductor body, the exposure unit having an inlet to which air flow is introduced; and an air blowing unit that produces the air flow that is introduced to the exposure unit from an air blow opening that is provided at a position that is in correspondence with a position of the inlet of the exposure unit.
