Abstract: An image forming apparatus comprises a transferer transferring a toner image on an image carrier onto a sheet, and facing the image carrier; a fixer fixing the toner image on the sheet; and a controller applying transfer voltage for transferring the toner image onto the sheet, wherein the transferer defines a transfer nip for passing the sheet between the image carrier and the transferer, the fixer includes a heating portion and a pressing portion, and passes the sheet after passing through the transfer nip through a fixing nip between the heating portion and the pressing portion, and the controller controls the transfer voltage in such a way that transfer current flowing through the transfer nip is made constant at a setting value, and increases the setting value of transfer current after a leading end of the sheet passes through the transfer nip and before it passes through the fixing nip.

Abstract: A document feeder constituting an image forming apparatus includes a paper feeder to supply a document to a document transport path, a first transporter to transport the document toward image reading positions, and a second transporter to transport the document toward the document discharging tray while supplying the document to the image reading positions. Furthermore, the document feeder includes a motor provided on the first frame, a first driver provided on the first frame and to transmit driving force generated by the motor to the paper feeder and the first transporter, a second driver provided on the second frame and to transmit the driving force generated by the motor to the second transporter, and a second driver to transmit the driving force generated by the motor to the second transporter, and a relay transmission member to transmit the driving force generated by the motor to the second driver.

Abstract: A channel box has a hollow elongated portion and accommodates a plurality of nuclear reactor fuel rods inside the hollow elongated portion, wherein the hollow elongated portion is constituted by a plurality types of silicon carbide composite materials. The channel box has a shape that can be achieved by applying the silicon carbide composite material and can increase earthquake resistance and improve functions and performance as a fuel assembly.

Abstract: This sheet separating device 50 includes: a release member 51 provided facing a rotating member (such as a fixing belt 43) arranged on a sheet transport path, and which extends toward the surface of the rotating member; a support member 54 that supports both ends of the release member 51; and a separating tip portion 71 arranged between the release member 51 and the rotating member. The separating tip portion 71 is provided so as to make contact with the rotating member, and is swingably attached to the support member 54.

Abstract: An image reading device includes a reading device body and a document feeder that is turnably attached on the upper side of the reading device body with hinge devices. An extended portion that extends outward from a rear frame is formed on a beam frame fixing the rear frame and a front frame of the document feeder at a predetermined interval, and a third coupling portion coupled to the turning member of the hinge device is formed in the extended portion.
