Abstract:
An image forming apparatus includes an image carrier unit, a developing device, a unit support frame, a retainer, and a developing device moving mechanism. The retainer swings in a first direction, in which the image carrier unit and the developing device are mounted in the unit support frame, to perform positioning of an image carrier, and swings in a second direction, in which the image carrier unit and the developing device are drawn out from a main body of the image forming apparatus, to unlock a positioned state of the image carrier. The developing device moving mechanism associates with the swing of the retainer in the first direction to dispose the developing device at a developing position, and associates with the swing of the retainer in the second direction to dispose the developing device at a separation position.
Abstract:
A liquid container includes a pack main body and a covering body. The covering body covers a part of the pack main body and is more hardly deformable than the pack main body. The pack main body includes a trunk part, a pair of sealing parts and a spout. The trunk part is formed into a rectangular cylindrical shape in a state where the ink is stored. The pair of sealing parts seal both ends of the trunk part. At least one of the sealing parts is formed into a gabled roof shape having a pair of flat portions facing each other in the thickness direction and a pair of gable portions facing each other in a width direction. The covering body includes a pair of covering flat plates covering at least a part of the pair of flat portions.
Abstract:
An inkjet recording apparatus of the present disclosure includes a recording head, a supply unit, a supply path, and a circulation path. The supply unit supplies liquid to the recording head. The liquid passes through the supply path to be supplied from the supply unit to the recording head. The liquid passes through the circulation path to return from the recording head to the supply unit. The supply path is provided with a supply coupling, and the circulation path is provided with a circulation coupling. Such part of the supply path as is located on an upstream side with respect to the supply coupling and such part of the circulation path as is located on a downstream side with respect to the circulation coupling are connected to each other by the bypass path which is switchable between a communicating state and a cut-off state.
Abstract:
An image forming apparatus includes an image forming section including an image carrier and a developing device, and a developer recovery mechanism. The developing device includes, a developer carrier, and a developer discharge portion. The image forming section incorporates a developing device employing a first developing method where toner is caused to adhere to the image carrier by a magnetic brush formed on the developer carrier, or a developing device having a toner carrier between the developer carrier and the image carrier, and employing a second developing method where a toner layer is formed on the toner carrier by a magnetic brush formed on the developer carrier, and toner is caused to adhere to the image carrier by the toner layer formed on the toner. These developing devices, in the image forming section, each have a same positional relationship between the developer discharge portion and an image-carrier rotation shaft.
Abstract:
An ink heating device comprising an ink container that includes an ink pack filled with ink, and a case housing the ink pack and having a first opening and a second opening, and a blower that sends warm air into the case through the first opening. The warm air is discharged through the second opening.
Abstract:
An image forming apparatus includes an image carrying member unit, a development device, a developer collection mechanism and a unit support tray. The developer collection mechanism is arranged on a downstream side in a first direction where the development device and the image carrying member unit are fitted into the main body of the image forming apparatus and the toner discharge portion of the image carrying member unit is coupled to the developer collection mechanism. The unit support tray is provided such that the unit support tray can be moved horizontally in the first direction and a second direction where the development device and the image carrying member unit are removed from the main body of the image forming apparatus; the unit support tray is moved in the first or second direction such that the toner discharge portion and the developer collection mechanism are coupled or the coupling is cancelled.
Abstract:
A developing device of the present disclosure includes a developing roller, a toner feeding roller, a thickness regulating member, and a casing. The toner feeding roller feeds toner to the developing roller. The thickness regulating member is disposed opposite to the toner feeding roller at a predetermined distance from the toner feeding roller, and the thickness regulating member regulates a thickness of the toner carried on the toner feeding roller. The casing holds therein the developing roller, the toner feeding roller, and the thickness regulating member. The thickness regulating member is formed in a roller shape and rotatable.
Abstract:
A developing device according to the present disclosure is provided with a developing container, a first stirring conveyance member and a second stirring conveyance member that stir and convey a developer within the developing container, and a developer carrying member that carries the developer. The developing container includes a discharge passage where a developer discharge port for discharging surplus developer within the developing container is formed. In the discharge passage, a discharge screw having a rotation shaft and a spiral blade is disposed. Within the discharge passage, at a portion on an upstream side of the developer discharge port in a developer discharge direction, there is provided a discharge regulating member that regulates discharge of the developer.
Abstract:
A developing device includes a contact member and a developing adhesion member. The contact member is provided to an air releasing part communicating an inside and an outside of a developer case storing a developer containing a toner, in a condition being contactable with an agitating member agitating and conveying the developer in the developing case. The developing adhesion member is supported by the contact member and is configured to collect the developer within air flowing from the inside to the outside of the developing case and to receive vibration caused by agitating and conveying operations of the agitating member through the contact member.
Abstract:
A development device includes a sheet member, a support member, and a vibration applying device. The sheet member is disposed between a developer carrier and a blade to receive a developer falling from the developer carrier toward the blade. The developer carrier is disposed to face to an image carrier on which an electrostatic latent image is formed and configured to supply the developer to the image carrier in a facing area to the image carrier. The blade is configured to regulate an amount of the developer carried on the developer carrier. The support member holds the sheet member. The vibration applying device applies vibration to the sheet member. The sheet member is stretchable and flexible and is stretched over the support member.
