    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 image forming apparatus, includes an image carrier; a power supply; a charging member, to which the power supply applies a direct current (DC) charging voltage, to charge a surface of the image carrier; and a controller. The controller causes the power supply to apply, to the charging member, the DC charging voltage of a sum of a reference voltage VC and a correction amount α, so that a charged potential VD of the surface of the image carrier assumes a target value that is substantially equal to the reference voltage VC; and to increase an absolute value of the correction amount α to be added to the reference voltage VC in inverse proportion to an absolute value of the reference voltage VC, when the absolute value of the reference voltage VC is smaller compared to a case in which the absolute value of the reference voltage VC is greater.

    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.
