Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To avoid wasteful transfers and to prevent wasteful line use. SOLUTION: An incoming call is answered automatically and character message data that is sent from a calling end is stored in memory, when transfer is set in an automatic recording mode. When a specific transfer is selected and the calling side is discriminated as being a calling side that needs transfer which has been previously set based on telephone number data of the calling side which is acquired by originator's number notification, etc., (ST29 to ST32), a call is made to a transfer destination that corresponds to the calling side and the character message data stored in the memory is sent to the transfer destination (ST32, ST33 and ST35) after the transfer destination answers. With this, only message data from the calling side which needs transfer is sent to the transfer destination. Further, when the transfer destination does not answer, the call is stopped (ST34) after a prescribed time has passed. Also, when there are plural transfer destinations, the transfer operation is repeatedly carried out (ST37) until the entire transfer destinations are finished.

Abstract: PURPOSE:To obtain a recording image which has sufficient density and good stability by ending the contact of a developer which is supplied onto the surface of a developing electrode with the recording surface of a recording body at a position where the developing electrode is in process of approaching the recording surface of the recording body or at the closest position. CONSTITUTION:When a sleeve 13 is at a position where it approaches the recording surface of the recording body or at the closest position, the contact of the developer with the recording surface is ended. For the purpose, the developer carrying speed Vsl of the sleeve 13 in a recording area X is made faster than the developer carrying speed Vmg of a magnetic roller 14 to prevent a developer from remaining on the outer peripheral surface of the sleeve 13 on the downstream side of the recording area X, i.e. at the closest position x1. The position x2 where the developer finishes the contact with the recording surface of the recording body 1 is inside an electric field area A. Therefore, when the recording body 11 is conveyed as shown by an arrow (c) and enters an area B where there is no influence of an electric field produced by the application of a voltage to the recording electrode 12, no developer contacts the recording surface of the recording body 11.
