  • Patent number: 10705483
    Abstract: A particle collecting device includes a vent pipe having a channel space through which air flows, a first air blower that delivers air including a particle at a first end of the vent pipe into the channel space, a collector that is disposed to block a channel in the channel space at an intermediate part of the vent pipe and that collects the particle included in the air delivered by the first air blower, and a second air blower that collects the air traveling through the collector at a second end of the vent pipe and that delivers the air outward from the channel space. The first and second air blowers operate such that a first pressure in a first channel space extending from the first air blower to the collector and a second pressure in a second channel space extending from the collector to the second air blower are maintained to have a relationship in which the second pressure<the first pressure?atmospheric pressure. The first and second channel spaces are included in the channel space of the vent pipe.

  • Patent number: 10603935
    Abstract: An opening and closing mechanism includes an opening and closing door that is rotatably supported to be movable between a closed position where an opening of an apparatus body is covered and an opened position where the opening is opened, a link member provided in the apparatus body and rotatably supported by a rotary shaft, a guide member having a first guide surface that moves while being in contact with the link member in a case where the opening and closing door moves to the closed position and a second guide surface that moves while being in contact with the link member in a case where the opening and closing door moves to the opened position, and a switching member that guides the link member from the first guide surface to the second guide surface, in which the switching member includes a root portion and an arm extending from the root portion to an opposite side to the apparatus body, and a first rotational moment toward the first guide surface using the root portion as an axis is applied to the arm.

  • Patent number: 9459587
    Abstract: 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.

  • Patent number: 9400477
    Abstract: A cleaning device includes a cleaning member that includes a cleaning portion that cleans a light transmission member, which has a substantially elongated shape and which transmits light, and a support portion that supports the cleaning portion and a wall portion that is disposed on one end side of the light transmission member in a longitudinal direction of the light transmission member and that has a surface that is formed along a direction that intersects the longitudinal direction of the light transmission member. The cleaning member and the wall portion each have a configuration in which when an end of the cleaning member makes contact with the wall portion and is pressed, the support portion is bent in a convex manner toward a side opposite to a side on which the light transmission member is disposed.

  • Patent number: 9298159
    Abstract: A removal mechanism includes a removing member, an accommodation section, a receiver, and a cooling path. The removing member rubs against an extraneous-matter-adhered member, to which extraneous matter is adhered, so as to remove the extraneous matter therefrom. The accommodation section accommodates therein the extraneous matter removed by the removing member. The receiver receives, at a lower side of the accommodation section, the extraneous matter spilling out and dropping from the accommodation section. The cooling path allows gas so flow therethrough so as to cool the accommodation section from outside thereof. The cooling path is spatially isolated from a passage chamber through which the extraneous matter dropping from the accommodation section toward the receiver passes, an accommodation chamber for the extraneous matter in the accommodation section, and a chamber above the receiver that receives the extraneous matter.

  • Patent number: 9141080
    Abstract: A drawer member that is capable of being drawn out from an image forming apparatus body and that includes a fixing unit that heats and fixes an image onto a recording medium, a first flow path that is formed around the fixing unit and that causes air that is heated by heat, which is discharged from the fixing unit, to circulate, and a second flow path that is formed adjacent to the first flow path on a side opposite to the fixing unit and in which air having a temperature lower than a temperature of air, which circulates in the first flow path, circulates.
