摘要：
A latent-image measuring device that measures the state of a photoconductor. The latent-image measuring device emits a charged-particle beam to the photoconductor to detects a charged-particle signal obtained through the emission of the charged-particle beam. The latent-image measuring device then exposes the photoconductor a plurality of times to form electrostatic latent images on the photoconductor, and measures an amount of change in latent-image depth while changing a time interval between a plurality of exposures.
