PROBLEM TO BE SOLVED: To provide a device and method for measuring an electrostatic latent image, capable of measuring charge distribution or potential distribution occurring on the surface of a photoreceptor at high resolution of micron order, and to provide an image forming device using a measured photoreceptor. SOLUTION: A photoreceptor sample 20 is irradiated with an electron beam so as to be charged; an electrostatic latent image is formed by an exposure section 6; an emission electron from the photoreceptor sample 20 is detected by scanning by the electron beam; and the electrostatic latent image distribution of the photoreceptor sample surface is measured, based on the detection signal. The exposure section 6 includes an LD light source 61, a light deflector 65, a synchronous signal-generating means for generating a synchronization signal at an end of a scanning range of the laser beam, and a write-in timing signal generating means for generating an emission timing control signal, when the laser beam scans the photoreceptor sample surface based on the synchronization signal. The distribution of the electrostatic latent image is measured at a predetermined timing, after the end of the exposure by the exposure section 6. COPYRIGHT: (C)2011,JPO&INPIT |
