Abstract
An electrostatic latent image measuring device includes a charged particle optical system which irradiates an electron beam and charges a photoconductor sample, an exposure optical system which forms an electrostatic latent image on a surface of the photoconductor sample, and a scanning unit which scans the surface of the photoconductor sample by the electron beam, a distribution of the electrostatic latent image on the surface of the sample being measured by a signal detected by the scanning.
