摘要:
An image forming apparatus includes a photosensitive member drum, a charging device for charging the photosensitive member drum, an image exposure device for image-exposing the photosensitive member drum, and an electric charge erasing device for erasing an electric charge outside an image-exposing area of the photosensitive member drum, wherein the electric charge erasing device is provided with a light emitting element and an optical element for lowering an amount of light which is incident on a border between the image-exposing area and an outside area thereof from the light emitting element.
摘要:
A developing device includes a container, a stirring and transferring unit, a replenishing unit, and a discharging mechanism. The container contains developer including toner and carrier. The stirring and transferring unit is located in the container to mix and stir the toner and the carrier, and circulates the developer in the container. The replenishing unit replenishes the container with developer from an opening of the container. The discharging mechanism discharges surplus developer out of the container, and is located on a rotation shaft of the stirring and transferring unit.
摘要:
A cleaning unit includes a first blade and a second blade. The first blade is in contact with an image carrier or a paper carrier and removes adhered substances remained on surface of these. The second blade has an abrasive layer that is formed by including abrasive particles in an elastic material and is disposed in the downstream side of the first blade. The second blade is allowed to be in contact with the image carrier 1 or the paper carrier. Volume occupancy of abrasive particles in an area of contact of the second blade with either the image carrier or the paper carrier is not less than 50 percent and not more than 90 percent.
