PURPOSE:To provide a record image with little fogging by forming recesses and projections continuing along the moving direction of a carrier on a face facing a carrier of an electric control means and controlling sufficiently the movement of toner to be fed. CONSTITUTION:Carried toners 6 are transported by the rotation of a toner carrier roller 14, and the toners on the roller 14 are fed under an aperture 6 while being rubbed by an insulating sheet 2 of an aperture electrode 1. At that time, grains of the toner 16 are restricted by a channel section formed on the sheet 2 to provide the extremely orderly state. That is, respective grains of toner are caught in the channel, and the toners of extremely large movement amount or the remaining toners can be controlled by the restriction. In other words, the movement of toners of irregular movement properties gets less, and a toner group of uniform movement properties is formed. The movement of respective tones is controlled in the above-said manner, and irregular toners are not generated. Thus an image of superior recording quality without fogging can be provided. |
