摘要： PROBLEM TO BE SOLVED: To provide an electrostatic latent image forming apparatus for outputting the same images at a high speed without generating much downtime in rewriting images by outputting the same images at a high speed without remarkably reducing photoreceptor life, and also to provide an electrophotography recording method.
SOLUTION: A first electrification image making roller 2 is irradiated with laser light by a laser generating device 1 to form irregularity images on the surface of the first electrification image making roller 2. The first electrification image making roller 2 is brought into contact with a photoreceptor drum 4 with a rotary rotating device 13. A voltage is applied on the electrification image making roller 2 to form latent images corresponding the irregularity images on the photoreceptor drum 4. The same images are output at a high speed by repeating the electrostatic latent image forming process, a developing process, the transfer process, the removing process, and the discharge process. The irregularity images of rewriting images are formed on the second electrification image making roller 12 between them, and images are switched without generating much downtime by switching a rotary rotating device 13.
