摘要:
A developing device includes a housing to store a powder, a developing roller to hold the powder, a supplying roller to supply the powder to the developing roller, a regulator to regulate the powder held by the developing roller, a powder conveyer to convey the powder for image forming, a first powder storing chamber, and a second powder storing chamber. The powder conveyor includes a first conveying part that includes a rotating axis, and a conveying surface inclined with respect to the rotating axis along a direction of the rotating axis. The powder conveyor further includes a second conveying part that includes a conveying surface parallel to the rotating axis along the direction of the rotating axis, and the first conveying part and the second conveying part are disposed alternately along the direction of the rotating axis.

A developing device is provided. The developing device includes a developer carrier, a regulator, a first developer storing chamber, a plurality of conveyers disposed within the first developer storing chamber, a second developer storing chamber in communication with the first developer storing chamber, and a supply member disposed within the second developer storing chamber. The developer carrier carries developer on its surface and supplies developer to a latent image carrier carrying a latent image. The regulator regulates the thickness of developer on the surface of the developer carrier. The first developer storing chamber stores developer separated from the developer carrier by the regulator and is to be supplied with fresh developer. Each of the plurality of conveyers coveys developer in a different conveyance direction. The second developer storing chamber is to be supplied with developer from the first developer storing chamber. The supply member supplies developer to the developer carrier.

A toner container includes a substantially tetrahedral toner-containing portion having an openable edge to discharge toner contained in the toner-containing portion, and a reference fold along which the toner container is foldable after the openable edge is opened. The reference fold extends from the openable edge and is provided on medians of two triangular faces of the toner-containing portion adjoining each other along the openable edge.

A seal includes a photoreceptor contacting portion to contact a photoreceptor, and a charge roller contacting portion to contact a charge roller. The photoreceptor contacting portion removes toner on the photoreceptor, and the charge roller contacting portion removes the toner on the charge roller, when the seal is mounted along the photoreceptor.

In a color printer in which a drive force of a fixed gear that rotates not in both a forward direction and a reverse direction but in either one direction only is transmitted to a discharging unit, a swing gear is attached to a branch guide via a switching link and a transmission link as a link mechanism. When a solenoid mechanism starts driving, the transmission link rotates. In accordance with the rotation of the transmission link, the switching link rotates, so that a switching among a discharge conveying path, a duplex-printing conveying path, and a switchback conveying path by the branch guide and a switching of a rotating direction of a transmission gear can be simultaneously performed.

A sheet-discharging device includes an upper discharging roller, a lower discharging roller, and a protruding member. The protruding member allows discharging of a sheet to outside from the nip between the upper discharging roller and the lower discharging roller, and prevents taking-in of a sheet that has already been discharged.

A conveying device conveys a sheet of non-blank recording medium recorded with an image formed in an image forming unit, and includes a container that is detachable and contains a sheet of blank recording medium, a feeding unit that feeds the blank recording medium from the container, and a recirculating path that leads the non-blank recording medium to the feeding unit. The recirculating path is disposed lateral to the image forming unit. A part of the recirculating path is integrated into the container and forms a reversing path that leads to the feeding unit. At least one of surfaces of the reversing path can be exposed.

An image forming device is disclosed. The device includes a toner-image forming unit which forms a toner image; a transfer unit; a fixing unit; a paper-output unit; a drive unit; a first drive-power transmission gear; a second drive-power transmission gear; a gear housing; a first positioning unit which positions the fixing unit relative to a device body; and a second positioning unit. The second positioning unit positions the paper-output unit relative to the device body in the direction of a gap between the first drive-power transmission gear and the second drive-power transmission gear by engaging the gear housing with the device body.

A sheet discharge roller has a contact portion in contact with a feed roller and a noncontact portion not in contact with the feed roller. The sheet discharge roller includes a kick-out unit having a projected portion and a recess portion on one end of the noncontact portion in the circumferential direction. A reverse roller also has a contact portion in contact with the feed roller and a noncontact portion not in contact with the feed roller. The reverse roller includes a large-diameter portion on its one end in a direction opposite to a direction of the kick-out unit. The large-diameter portion has a diameter larger than a diameter of the contact portion.
