Abstract: An image forming apparatus includes an image bearing member, a charging unit, a laser scanning unit, a developing unit, a transfer member, a recording medium conveyance path, a cleaning unit, and a heating element. The recording medium conveyance path includes a resin member that forms a conveyance surface. The resin member has a concave portion at a location closer to the transfer member than to the image bearing member. The heating element for heating the image bearing member is accommodated in the concave portion. The heating element is disposed downstream from the contact point between the image bearing member and the transfer member in the conveyance direction in which a recording medium is conveyed through the recording medium conveyance path. The developing unit is located upstream from the contact point between the image bearing member and the transfer member in the conveyance direction of the recording medium.

Abstract: 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.
