Abstract

Official abstract text for this publication.

A charging device includes a housing, a charging roller, and a brush roller. The housing is disposed adjacent to an optical path of light emitted an the exposure device to irradiate a photoconductor. Charging roller is rotatably supported in housing, and is configured to charge a circumferential surface of the photoconductor through contact. Brush roller is rotatably supported in housing together with charging roller, has multiple brush hairs flocked on a base shaft thereof extending in a longitudinal direction of the charging roller, and is configured to clean a surface of charging roller when brush hairs are brought in contact with charging roller. Furthermore, a predetermined segment of housing is located in a space within a predetermined distance toward a side of housing from the optical path, and is formed from a material having a charge property equivalent to that of the brush hairs.
