の静電記録装置。[Claims for Utility Model Registration] (1) A photoreceptor having a circumference longer than the length of one copy, a developing device with a variable developing bias value, and a light source that uniformly illuminates the photoreceptor, The photoreceptor is rotated twice, and the first development is performed at a level of charging, image exposure, and development bias that does not cause background stains, and then after the entire surface is exposed to light, the second development is performed by changing the development bias. An electrostatic recording device characterized in that it performs transfer. (2) The electrostatic recording device according to claim 1, which is a utility model registration, characterized in that the light source for uniformly irradiating the photoreceptor also serves as a light source for another purpose for irradiating the photoreceptor.
