Abstract

PURPOSE:To always renew the magnetic toner on doner drum surface and obtain stable recording images by disposing the first magnet in the rotating doner drum of the direct recorder and the second magnet in the rotating toner-supplying sleeve in specific positions. CONSTITUTION:In the direct recorder of forming images according to document and picture information on the recording material 10 positioned between a recording electrode 1 and a doner drum 2, the magnetic flux density B1 of the first magnet 30 disposed within the doner drum 20 which is rotated in the arrow direction about O is disposed on the advance side in the rotating direction of the drum 20 than the line L connecting O, P and the magnetic flux density B2 of the second magnet 70 disposed within the toner supplying sleeve 60 rotated in the arrow direction about P is positioned on the delay side in the rotating direction of the drum 20 than the line L (angles theta1,theta2 are preferably about 5 deg.). In addition the abovementioned both magnetic flux densities are preferably B1>B2.
