An intermediate transfer body is provided. An intermediate transfer body includes an intermediate transfer belt and a belt cleaning section including a cleaning blade. A plurality of projecting portions extending in parallel with a rotation direction of the intermediate transfer belt are provided on a surface of an elastic layer of the intermediate transfer belt. The cleaning blade is formed such that a width W1 of one end in a lateral direction thereof is longer than a width W2 of the elastic layer in a width direction of the intermediate transfer belt.

In order to provide a sheet postprocessing device which positively prevents an uneven image from occurring without using any means that spoil the appearance when a set of sheets is ejected onto the ejection tray, and which stacks sets of sheets without disarray, in the present invention, after sheets have been ejected from the copying machine and have been subjected to a stapling operation that is one of postprocessing operations, the sheets are ejected onto an offset tray by an ejection roller. The ejecting rollers are provided with a lifting mechanism for lifting the leading portion of the set of stapled sheets with regard to the ejecting direction.

Provided are a laser-bonded component and a production method for same that ensure sufficient bonding strength using little laser energy and which cause little increase in surrounding temperature. A nickel layer, being a surface layer, is formed having sufficient thickness on the upper surface of a copper plate that is uppermost amongst at least two superposed copper plates, a laser is irradiated from above the nickel layer, a re-solidification section formed by fusing and alloying the copper in the copper plates and the nickel in the nickel layer is formed through to inside the bottommost copper plate, and the copper plates are bonded together. The re-solidification section having high breaking strength is formed by the alloying of the nickel and the copper. As a result, the copper plates can be bonded with a small welding surface area and little laser energy.

A belt cleaning apparatus includes a cleaning blade and a waste toner case. The cleaning blade is a plate-like elastic member that extends in parallel with a width direction of an intermediate transfer belt and is provided so that one end of a lateral direction thereof abuts on an outer peripheral surface of the intermediate transfer belt. The waste toner case supports the other end in the lateral direction of the cleaning blade. The cleaning blade is formed such that a width W1 of the one end in the lateral direction thereof is longer than a width W2 of an elastic layer in the width direction of the intermediate transfer belt.
摘要:
Highly-accurate approximate positional information is transmitted to a communication terminal.An approximate positional information DB 23 of a SUPL server 20 included in a positioning support system 10 includes approximate positional information which is used for positioning calculation at the communication terminal 60 and which indicates a position of a cell C1 in which the communication terminal 60 exists and a cell ID identifying the cell C1, with approximate positional information and the cell ID being associated with each other. Based on a positioning information transmission request which includes a cell ID and which is transmitted from the communication terminal 60, approximate positional information stored in the approximate positional information DB 23 is acquired and transmitted from a communication unit 21 to the communication terminal 60. In addition, positioning result information that is information indicating a result of the positioning calculation which is transmitted from the communication terminal 60 is received and, based on this information, approximate positional information stored in the approximate positional information DB 23 is updated by a control unit 22. The accuracy of approximate positional information is enhanced due to the approximate positional information stored in the approximate positional information DB 23 being updated based on positioning result information.

An image forming apparatus includes a transfer belt unit which has an intermediate transfer belt for supporting toner images and primary transfer rollers for pressing the intermediate transfer belt against corresponding photoreceptor drums and moves the intermediate transfer belt along the surface of each photoreceptor drum to transfer the toner images to the intermediate transfer belt. The intermediate transfer belt is formed so as to be 30 μm to 50 μm in average thickness, each primary transfer roller is arranged at a position, along the moving direction of the intermediate transfer belt, which is deviated downstream with respect to the moving direction from the position where the intermediate transfer belt is in contact with the photoreceptor and which is projected toward the photoreceptor drum side so as to press the intermediate transfer belt against photoreceptor with a nip pressure ranging from 10 gf/cm2 to 40 gf/cm2.

摘要:
An organic insulating coating formed on a substrate is composed of two layers of a first parylene coating and a second parylene coating. Heat treatment is performed to at least the first parylene coating after being formed, at a temperature below 125° C. for two hours. Then the second parylene coating is formed on the first parylene coating. Occurrence of pinholes is thus prevented at least in one of the two layers of the organic coatings, with the result that insulating properties of the coatings are improved.
