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:
An image forming apparatus includes a connection mechanism in electrical contact with a contact. The connection mechanism includes a terminal member, a power supplying member, an insulating member, and a holding member. The terminal member makes contact with the contact. The power supplying member feeds electric power to the contact via the terminal member and urges the terminal member toward the contact. The insulating member covers the terminal member. The holding member holds the terminal member covered with the insulating member. The terminal member, at a tip end portion of it that projects from the holding member, makes contact with the contact. The insulating member covers at least an entire region, except a contact portion with the contact, of the terminal member that projects from the holding member.
Abstract:
A lighting device includes a light source, a light guide, a light guide cover, and a unit frame. The light guide is in a bar form and, while guiding light that has entered from the light source along the axial direction, sends forth the light. The light guide cover holds the light guide. The light guide cover is attached to a unit frame. The light guide cover includes a main body portion and a plurality of light guide holding portions provided along the longitudinal direction of the main body portion and holding the light guide at a plurality of places, and a plurality of guide engaging portions provided along the longitudinal direction of the main body portion. The unit frame has a cover fitting face to which the light guide cover is fitted and a plurality of cover guides with which a plurality of guide engaging portions engage respectively.
Abstract:
A cover member attachment/detachment structure includes a first engagement part and a second engagement part. The first engagement part is formed in one of a portion to be protected or a cover member attached to the portion to be protected. The second engagement part is formed in the other of the portion to be protected or the cover member attached to the portion to be protected. The second engagement part is capable of engaging with the first engagement part. The first engagement part is made of magnetic material. The first engagement part is magnetically movable from an outside of the cover member without contact between a locking position where the first engagement part is engaged with the second engagement part and a lock releasing position where the first engagement part is disengaged with the second engagement part.
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.
Abstract:
A developing device of the present disclosure includes a developing roller, a toner feeding roller, a regulating blade, a blade holding member, a toner receiving member, and a casing. The regulating blade regulates a thickness of toner carried on the toner feeding roller. An air flow path is formed inside the blade holding member. The toner receiving member, the regulating blade, and the blade holding member each include a slit hole that leads to the air flow path.
