IPC: B41J2/39
Filed: 2001-01-31
Abstract: PROBLEM TO BE SOLVED: To write a latent image stably and to lower the applying voltage while enhancing stability in the writing position control of the latent image. SOLUTION: An electrostatic latent image is written on an image carrier 2 by means of the writing electrode 3b of a writing unit 3.
