摘要： An image forming apparatus having a single driving source to move a charging roller and a transfer roller to be in contact with and separated from a photoreceptor to place the charging member and the transfer member in various states in relation to the photoreceptor as the image forming apparatus demands. The single driving source includes first and second cams having a common axis of rotation. One cam is used to move the charging member and the other cam is used to drive the transfer member. The control system is provided with a device for recognizing the current positions of the charging member and the transfer member in relation to the photoreceptor and a device for prescribing future positions of the charging member and the transfer member in relation to the photoreceptor after having been driven. The apparatus further includes a controller which operates the driving source until the charging member and the transfer member come to a state prescribed as the state to reach after from the current position.

摘要： 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.

摘要： 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.
