Abstract

PURPOSE: To execute image recording of stable quality by preventing a magnetic fluid from sedimentation and condensation, by shortcircuiting the magnetic path of a permanent magnet and eliminating the magnetic flux at a recording indicator tip section.
CONSTITUTION: The current passing through an electromagnet 21 is cut off when recording is not executed, a magnetic shortcircuiting board 20 is moved in the direction of an arrow B by the force of a spring 23, and it is tightly attached onto a swelling magnet 8. At this time, as a setting is made so that a magnetic shortcircuiting boards 19 and 20 tightly contact with each other at a section C, the swelling magnet is shortcircuited. And therefore, magnetization of a stylus section 7 becomes weak and a magnetic fluid toner 11 does not adhere to it. Further, the magnetic fluid toner 11 on the swelling magnet 8 is also removed by means of the magnetic short- circuiting board 20. At the time when recording is executed, the electromagnet 21 is driven to move the magnetic shortcircuiting board 20 in the direction of an arrow A prior to an image-recording operation, and the shortcircuiting board 20, the magnet 8 and the stylus 7 are separated from one another. And therefore, the toner 11 is made to flow by the magnetic force and a prescribed magnetic circuit is formed.
