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&#x3c;the first pressure&#x2264;atmospheric pressure. The first and second channel spaces are included in the channel space of the vent pipe.

A gas purification device includes an inflow port provided in an upper part of the gas purification device in a gravitational direction so that gas flows therein, a removing member that removes powder contained in the gas when the gas passes through the removing member, the removing member being disposed at a position such as not to overlap with the inflow port when viewed from above in the gravitational direction, and an outflow port provided in a lower part of the gas purification device in the gravitational direction so that the gas flows out therefrom after passing through the removing member.

It is a sealing member that seals a gap between one member and the other member, including: a mounting section that has a portion coming into contact with the other member; and an extension section that extends from a side of the mounting section to a side of the one member and is configured to approach the mounting section while coming into contact with the one member by receiving a force from the one member; and a recess that is provided between the mounting section and the extension section and is formed from a part of the mounting section to a part of the extension section, and is recessed from a surface of the mounting section on the side of the one member and a surface of the extension section on a side of the other member.

Sealing member, storage member, and image forming apparatus

An apparatus includes a device that includes a driving source, an opening and closing door that is opened and closed by rotational operation about a rotating shaft with respect to a body of the apparatus, and an elastic part that is provided at the body of the apparatus, that is elastically deformed by contact with a first portion of a part of the opening and closing door on the side of the rotating shaft and blocks a gap between the first portion and the body of the apparatus when the opening and closing door is closed, and that is elastically deformed by contact with a second portion of the opening and closing door that is different from the first portion when the opening and closing door is opened.

Image forming apparatus with opening and closing door

An image forming apparatus includes: a transfer belt having a surface onto which a toner image is transferred directly or through a transfer medium; plural image forming units that are aligned along a moving direction of the surface of the transfer belt and form the toner image; a support member that supports the transfer belt; a flow path forming member that forms a flow path along the moving direction of the surface of the transfer belt, has plural suction ports through which floating fine toner particles occurring in the plural image forming units are sucked into the flow path, and is disposed at the transfer belt side with respect to the support member; and an exhausting unit that sucks the floating fine toner particles through the suction ports into the flow path, and exhausts the sucked floating fine toner particles from the flow path.

A cooling device that cools the inside of an image forming apparatus provided with a developer carrier that carries an image developed with a developer while being rotated. The cooling device includes: a counting unit that counts an accumulative number of rotation of the developer carrier; and a fan that cools the inside of the image forming apparatus. The cooling device further includes: a calculating unit that calculates an abrasion amount of the developer carrier in which the accumulative number of rotation counted by the counting unit is used as at least one variable; and a controlling unit that actuates the fan with cooling efficiency according to the abrasion amount calculated by the calculating unit.

An image forming apparatus includes a main body, a post-processing unit, a transport unit, a filter and a suctioning/exhausting unit. The post-processing unit is disposed adjacent to the main body. The post-processing unit performs predetermined post-processing on a recording medium on which an image is formed in the main body. The transport unit transports the recording medium from the main body to the post-processing unit. The suctioning/exhausting unit suctions air in the transport unit and exhausts the suctioned air through the filter to an outside of the main body.

Image forming apparatus capable of reducing disagreeable odor and volatile organic compounds

An image forming apparatus includes a recoding-medium stacking portion, a recording-medium ejecting portion and a auctioning/exhausting unit. The recording-medium ejecting portion ejects a recording medium on which an image is formed, to the recording-medium stacking portion. The suctioning/exhausting unit suctions air in a vicinity of the recording-medium ejecting portion. The suctioning/exhausting unit exhausts the suctioned air though a filter to an outside of a main body of the image forming apparatus.
