There is provided an inkjet recording apparatus including: a plurality of ink ejectors each having a nozzle array in which two or more nozzles each of which ejects ink are one-dimensionally arranged; a support member to which the plurality of ink ejectors are attached at positions different from one another in a predetermined arrangement direction in a state where the nozzle array is oriented in the arrangement direction; and a support member deformer that deforms the support member in a direction in which a deflection of the support member is reduced.

Inkjet recording apparatus

A toner collection container detachably incorporated in an electrophotographic image forming device in order to collect toner to be discarded from an image former of the device includes: a housing including a hollow capable of storing discarded toner, and incorporated between an air inlet port and the image former in a space surrounded by a chassis of the image forming device; and at least one duct being formed of a cylindrical or tubular member that penetrates a storing region in the hollow of the housing from a side closer to the air inlet port to a side closer to the image former out of side walls of the housing, or formed of a recess included in a bottom surface of the housing and recessed toward the storing region, the duct guiding external air flowing from the air inlet port to a side where the image former is positioned.

A sheet post-processing device is mounted in an image forming apparatus that includes an image reading unit and an image forming unit. The image forming unit is located under the image reading unit with a space therebetween. The sheet post-processing device includes: a first tray that is located in the space and houses a sheet ejected from the image forming unit; a post-processing unit that is located in the space and performs post-processing on a sheet in the first tray; a transfer member that, after the post-processing is performed on a sheet in the first tray, transfers the sheet to a front side of the image forming apparatus; and a second tray that is located closer to the front side of the image forming apparatus than the first tray and houses a sheet transferred by the transfer member.

Sheet post-processing device and image formation system

Sheet transport device including: first tray having receiving area receiving sheets ejected in first direction; second tray in second direction intersecting first direction with respect to first tray; transporter causing pushing member to move between first and second positions at respective sides of receiving area along second direction, second position closer to second tray than first position, transporter transporting first sheet set to second tray by putting pushing member in contact with end of first sheet set facing first position and causing pushing member to move from first to second position when first sheet set is ejected onto first tray; and direction changer causing guide member to guide, in subsequent second sheet set, at least sheet ejected while pushing member moves across receiving area and to change sheet traveling direction to upward direction over pushing member by putting guide member in predetermined angle with respect to horizontal direction.

Sheet transport device and image forming system

An image forming device having a printer unit, a post-processing unit, and an eject tray. The printer unit forms images on recording sheets, and the post-processing unit performs processing on a recoding sheet stack composed of one or more recording sheets output from the printer unit before the recording sheet stack is ejected onto the eject tray. The image forming device includes: a buffer unit that, while a first recording sheet resides in the post-processing unit for the post-processing, holds a second recording sheet therein, the second recording sheet output from the printer unit subsequent to the first recording sheet; and a reverse path that reverses recording sheets when the image forming device performs duplex printing. In a plan view of the image forming device taken along a vertical direction, the post-processing unit, the buffer unit, and the reverse path at least partially cover one another.
