摘要： PROBLEM TO BE SOLVED: To surely prevent adhesion of foreign substances such as paper dust and other dust to an inkjet recording head without lowering recording quality. SOLUTION: In the inkjet printer 1, each of a nozzle plate side gap H2 and a supporting member side gap H3 is set so that the gap H3 becomes smaller than the gap H2 for at least one or more of a plurality of kinds of recording papers (different in thickness t) supposed to be used. Coulomb force which acts on the paper dust and the like d by an electric field generated in the supporting member side gap H3 can be made larger than Coulomb force which acts on the paper dust and the like d by an electric field generated in the nozzle plate side gap H2. The paper dust and the like d adhering to the recording paper P (particularly an end part) is drawn more strongly to the supporting member 17 side than to the nozzle plate 16a side, and accordingly flying and adhesion of the paper dust and the like d to the nozzle plate 16a can be surely prevented.

摘要： PROBLEM TO BE SOLVED: To obtain a writing head capable of touching a latent image carrier stably, while preventing waving or cockling, by eliminating a local low rigidity region between writing electrodes or between wiring patterns. SOLUTION: In a recording head 3 having a plurality of writing electrodes 3b arranged on a flexible supporting basic material 3a and forming an electrostatic latent image on a latent image carrier 2 by touching or approaching the latent image carrier 2 and applying a writing voltage thereto, and in an image forming apparatus 1 equipped with the writing head 3, a member 12 for stretching the flexible supporting basic material 3a in the main scanning direction is provided in order to ensure rigidity the main scanning direction. Since a local low rigidity region does not exist between the writing electrodes 3b or between the wiring patterns, the writing electrode 3b can touch the latent image carrier 2 stably. Consequently, the writing head 3 can be prevented from waving or cockling, an electrostatic latent image is formed correctly on the latent image carrier 2 and print quality can be prevented from lowering.
