PHOTORECEPTOR CHARACTERISTIC EVALUATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a photoreceptor testing device for electrophotography not generating a measuring error caused by a size change of an opening part forming a test area.;SOLUTION: This photoreceptor testing device for the electrophotography has a discharger with no discharge area for discharge along a turn table direction other than the opening part, and is constituted to conform a length of the opening part measured along a radial direction of the turn table with a length of a discharge area of a charger, in a testing device for evaluating a characteristic of a photoreceptor for the electrophotography, having at least the turn table having the opening part capable of setting a photoreceptor sample piece for the electrophotography, a turn table rotating means for rotating the turn table at a high speed, a charging means for charging the photosensitive member sample piece for the electrophotography by corona discharge from a discharge wire, and an exposure means.;COPYRIGHT: (C)2006,JPO&NCIPI
