ABSTRACT:
A method and an apparatus for recording an image is disclosed, in which toner is supplied between a conductive recording drum covered with an insulating material and recording electrodes with the forward end thereof with a small gap from the drum and inclined at a great angle upstream of the direction of rotation of the recording drum. A toner carriage force is generated in the toner to flow out downstream by rotation of the recording drum. A permanent magnet is arranged in the recording drum to form a toner chain inclined at a great angle downstream of the recording drum from the forward end of the recording electrodes. The component of the magnetic force of the magnet in the direction of drum movement is balanced with the toner carriage force. Upon application of a recording voltage to the recording electrodes under this condition, the toner of the most downstream toner chain in contact with the drum surface develops a force of adhesion to the recording drum so that the drum rotates downstream with the toner attached thereon, thus forming an image due to the toner on the recording drum.
