Abstract

PURPOSE:To make it possible to obtain record images of high quality by maintaining such a condition wherein magnetic fluid substances are completely removed from the top end of a recording neelde and inside a supply route up to the end of the recording needle by seqparating such substances from those parts at the time of non-use. CONSTITUTION:At the time of recording, a bulging magent 13a is at the position of broken lines 25 and the position 25 is such a position where a recording electrode 2 is magnetized and a bulge is formed by causing magnetic fluid 6 to adhere to its top end and a bulge for appropriate recording is obtained. Upon completion of recording, a switch 7 is turned off, the level of magnetic fluid inside electrodes 4a, 4b becomes a position 17 and a small amount of magnetic fluid 19 adhers to and remains at the top end of the recording electrode 2. Upon completion of normal recording, after the level of magnetic fluid 6 inside the electrodes 4a, 4b composing a supply route is caused to come to the position of 17, the bulging magnet 13a is moved from the position 25 at the time of recording to the position 26 and it is caused to come close to the top end of the recording electrode 2. By the movement of the bulging magnet 13 to the position 26, strong magnetic force acts on the top end of the recording electrode 2, residual magnetic liquid 19 flies onto a recording paper 9 and is completely removed.
