PROBLEM TO BE SOLVED: To form an image free from nonuniformity in density without causing fixation of toner, by a constitution wherein a charged body flow control means is so disposed as to come into contact with a charged body on a charged body bearing means and the part of contact of the charged body flow control means with the charged body is formed in a projecting shape directed toward the side of the charged body bearing means. SOLUTION: A toner supply device 10 is provided in a lower part and a print head 1 as a charged body flow control means for controlling a flow of toner is provided in the upper part of the device, while a back electrode roller 22 is provided rotatably above the print head 1 with a space of about 1 mm held between. In a gap between the print head 1 and the back electrode roller 22, a recording medium 20 is carried in the direction of an arrow C by the rotation of the back electrode roller 22 in the direction of an arrow D and further by the rotation of carrying rollers 19, and others, while a heat fusing device 26 composed of a pressure roller and a heating roller in a pair is provided ahead in that direction. A pressure of contact of the charged body flow control means with the charged body bearing means is made uniform. |
