A developing apparatus includes a developer containing portion containing a developer having a weight average particle diameter of not more than 7 &mgr;m, a developer bearing member for bearing a developer, and an agitating member that agitates the developer contained in the developer containing portion. The agitating member is intermittently driven with respect to rotation of a developing sleeve. The agitating member is driven to rotate for one page every time the image forming apparatus performs a predetermined number of printing operations. A rod member having a crank-like shape may be used as the agitating member and both of the end portions serve as the center of rotation. By controlling the drive of the agitating member, it is possible to effectively adjust the supply of toner to the developing sleeve and prevent the density lowering phenomena caused due to inflow of a large amount of the new toner presented at the rear of the developing container. The agitating member may be positioned closest to the developing sleeve and may be arranged below the toner container. Accordingly, to these arrangements, the image density after printing a low print pattern can be prevented from being lessened to obtain a uniform image density even though a one-component magnetic developer having the weight average particle sized diameter of not more than 7 &mgr;m is used.

A process cartridge includes an electrophotographic photosensitive member, a developer for developing a latent image formed on the electrophotographic photosensitive member, a developer remaining amount detecting member for detecting a remaining amount of developer in the developer, and a non-volatile memory for memorizing information corresponding to at least the print number of sheets and the developer remaining amount in such a manner that such information can be read out and re-written by an image forming apparatus. The present invention also provides and electrophotographic image forming apparatus to which such a process cartridge can be detachably mounted.

In a V-ribbed belt used in a manner of bringing the back face as well as the bottom face into contact with pulleys, a hiding layer for hiding the texture of the belt is formed on a part of the side faces of the belt body, and a mark indicating the history of belt manufacturing is provided on the hiding layer. This prevents the occurrence of inconveniences resulting from the formation of the mark on the belt back face and keeps the mark recognizable for a long time.

A fuel vapor capturing canister includes a cylindrical casing having a communicating hole which is formed at one end so as to communicate with the atmosphere and another communicating hole which is formed at the other end so as to communicate with a fuel tank and an intake system of an engine. An adsorbent is accommodated in the casing so as to form at least one layer. A pair of partitioning plates partition the adsorbent layer longitudinally of the casing. A deflecting plate is disposed between the partitioning plates so as to protrude from an inner wall face of the casing inwardly of the same. The partitioning plates are open in the vicinity of sides of the deflecting plate respectively.

A method of performing an imprint process on each of a plurality of shot regions of a substrate, wherein each shot region includes at least one of at least one valid chip area and at least one invalid chip area, the invalid chip area including an inhibited area in which resin coating is inhibited, the imprint process for a shot region including both the invalid chip area and the valid chip area includes coating the valid chip area of the shot region with the resin, bringing a pattern surface of a mold into contact with the resin, and curing the resin, and in the step of coating, at least the inhibited area of the invalid chip area is not coated with the resin.
摘要:
An imaging apparatus for performing efficient signal processing depending on the operational mode. In the finder mode, a CCD interface 21a decimates horizontal components of image data supplied from an image generating unit 10 to one-third and moreover processes the decimated image data with data conversion and resolution conversion to produce Y, Cb and Cr image data which are routed to and written in an image memory 32 over a memory controller 22. In the recording mode, the CCD interface 21a causes the image data from the image generating unit 10 to be written in the image memory 32 via memory controller 22 after decimation and gamma correction etc. The camera DSP 21c reads out the image data via memory controller 22 from the image memory 32 to effect data conversion for writing the resulting data via memory controller 22 in the image memory 32.

摘要:
The present invention provides an apparatus including a calculating unit which calculates a first time serving as a time required to drive a stage in a non-scanning direction perpendicular to a scanning direction, and a second time serving as a time required to drive the stage in the scanning direction, both of which range from when exposure of one of the plurality of shot regions ends until exposure of the next shot region starts, and an adjusting unit which adjusts, when the first time is longer than the second time, one of a time for which an acceleration of the stage nonlinearly changes in the process of reversing the scanning direction, and a settling time taken for the stage to settle from when acceleration of the stage ends until exposure starts, so that the second time becomes longer than the first time in driving the stage in the scanning direction.
摘要:
A communication apparatus stores encrypted pieces having plural pieces as a part of a content encrypted, and number of transmission times. At least one first piece is encrypted by plural different encryption keys. The communication apparatus selects as priority pieces plural encrypted pieces corresponding to at least one first piece among the first pieces, based on number of untransmitted encrypted pieces of which number of transmission times is zero among plural encrypted pieces of which first piece is encrypted, and stores priority piece information specifying the priority piece. When a piece request is received from other communication apparatus, the communication apparatus determines an encrypted piece to be transmitted, based on priority piece information, and transmits the encrypted piece to the other communication apparatus.
