    Abstract: An elastic blade includes a contact edge to contact a contact object, an edge region including the contact edge and having a thickness smaller than or equal to 0.50 mm, and a backup region different in material or property from the edge region. The backup region is adjacent to the edge region on a cross section perpendicular to a direction in which the contact edge extends. The elastic blade has a converted Martens hardness X (N/mm2) in a range of from 0.9 to 2.9. The converted Martens hardness is defined as: X = S A S A + S B × h A + S B S A + S B × h B where SA represents a cross-sectional area (mm2) of the edge region, SB represents a cross-sectional area (mm2) of the backup region, hA represents a Martens hardness (N/mm2) of the edge region, hB represents a Martens hardness (N/mm2) of the backup region, and t represents the thickness (mm) of the edge region including the contact edge.

    Abstract: An elastic blade includes a contact edge to contact a contact object, an edge region including the contact edge, and a backup region different in at least one of material and physical property from the edge region and adjacent to the edge region on a cross section perpendicular to a direction in which the contact edge extends. The backup region is free of direct contact with the contact object. In the elastic blade, a converted elastic power X is from 57% to 90% and defined as X = S A S A + S B × e A + S B S A + S B × e B , where SA and SB represent cross-sectional areas of the edge region and the backup region on the cross section, eA and eB represent elastic powers of the edge region and the backup region, and t represents a thickness of the edge region in a direction perpendicular to the longer of two sides of the edge region on the cross section.

    Abstract: An image forming apparatus includes a rotatable image bearer, a charging member to contact a surface of the image bearer and charge the image bearer, an exposure device to expose the image bearer and form a latent image, a developing device to develop the latent image on the image bearer into a toner image, a transfer device to transfer the toner image from the image bearer onto a transfer medium, and a cleaning blade to contact the surface of the image bearer and remove toner from the image bearer after image transfer. The charging member has surface unevenness created by projections and recesses extending in a direction of rotation of the image bearer. The cleaning blade is configured to abrade projections formed on the surface of the image bearer.

    Abstract: An image forming apparatus forms a color image, and includes an endless intermediate transfer belt which rotates and carries a toner image and plural image forming units for plural colors arranged in tandem along the intermediate transfer belt. Each of the image forming units includes an image carrier which rotates and carries a latent image, a charging device which charges the image carrier, a development device which develops the latent image into a toner image, and a cleaning device which cleans the image carrier after the toner image is transferred to the intermediate transfer belt. The charging device of the extreme upstream image forming unit in the belt direction of rotation is a non-contact charging device not in contact with the image carrier. The extreme downstream image forming unit in the belt direction or rotation includes a lubricant application device which applies a lubricant to the image carrier.

    Abstract: An image forming apparatus includes a plurality of image bearers and a rotatable transferor. Images borne on the plurality of image bearers are transferred to the transferor. The transferor has an elastic power larger than an elastic power of each of the plurality of image bearers, and a difference in elastic power between the transferor and a most upstream image bearer in a rotation direction of the transferor is smaller than a difference in elastic power between the transferor and any other image bearer except the most upstream image bearer of the plurality of image bearers.

    Abstract: An image forming apparatus includes an image bearer to bear a latent image, a charging device to charge the image bearer, a developing device to develop the latent image on the image bearer, a cleaning device to clean a surface of the image bearer, a target component including at least one of the image bearer, the charging device, the developing device, and the cleaning device, and a temperature change suppression member opposed adjacent to or disposed in contact with an outer peripheral face of the target component. The temperature change suppression member suppresses a temperature change of the target component.
