ABSTRACT:
A recording method of forming a picture image directly on a recording sheet by a magnetic brushing process using a dry developing powder on the basis of an input picture signal not by forming an optical image directly on the recording sheet surface. The recording method comprising steps of disposing a transparent guide member against a nonmagnetic and conductive sleeve of a cylindrical shape which includes a permanent magnet member having a plurality of magnetic poles on its surface; so as to form a recording region applying a magnetic dry developing powder onto the sleeve, rotating the permanent magnet relative to the sleeve to form a magnetic brush at least in the recording region; passing a transparent recording sheet along the surface of the guide member so that the magnetic brush is brought near to or into contact with the recording sheet; and emitting a light signal based on a picture information signal to the guide member from its rear side to form a visible powder image on the surface of the recording sheet.
