PURPOSE:To enable images to be recorded simply through impressing a voltage according to an image signal on a counter electrode, by providing a conductive toner flight controlling member which comprises a plurality of minute opening parts and a plurality of controlling electrodes for controlling the passage of a toner through each of the minute opening parts. CONSTITUTION: A toner carrier 1 is rotated in the direction of an arrow, a conductive toner 5 is uniformly adhered to and supported on the surface of the toner carrier 1 by a blade member 6, and is fed toward a conductive toner flight controlling member 2. To record a powder image, the carrier 1 is rotated in the direction of the arrow to feed the conductive toner 5 toward the controlling member 2, while a counter electrode 3 is rotated to move a recording material 4 in the direction of an arrow. Simultaneously, an electrical signal for recording is inputted to a driving voltage impressing means 10, and a voltage is impressed on controlling electrodes 9 based on the signal, whereby the toner 5 is caused to fly toward the recording material 4 through minute opening parts 8 and adhere to the recording material 4, forming a visible image, namely, a powder image on the recording material 4. |
