In an example of the disclosure, a print apparatus component to be cleaned is rotated about a rotational axis. A cleaning element having a cleaning surface in contact with the print apparatus component is rotated. The cleaning element is oscillated in a direction parallel to the rotational axis. Rotation and oscillation of the cleaning element are varied according to a predetermined function to remove a residue from the print apparatus component.

An image forming apparatus includes a lubricant application device to apply a lubricant to a photoreceptor surface of the image forming apparatus, and a lubricant residual amount detector to detect a residual amount of the lubricant. The residual amount of the lubricant is compared to a predetermined amount, and a charging device charges the photoreceptor surface by selectively applying a DC voltage of varying voltage to the photoreceptor surface in response to the comparison of the residual amount of the lubricant to the predetermined amount.

An image forming apparatus includes an image bearing member, a developer bearing member, a fixing unit including a heating member, a rotary member which is heated by the heating member, and a nip area where the rotary member comes into contact with a sheet, and configured to perform fixing by heating a developer image transferred to the sheet and fixing the developer image to the sheet in the nip area, and a control unit configured to execute, while the fixing is not performed, a mode in which the image bearing member is rotated with the developer bearing member being in a separated position and the heating member is controlled such that a temperature of a portion of a surface of the rotary member, after the rotary member passes through the nip area, is maintained higher than the temperature of the portion during the fixing.

An image forming apparatus includes a developing unit and a supply amount increasing unit. The developing unit supplies oil-impregnated particles to an image carrier and develops an electrostatic latent image by a developer on the image carrier which is electrically charged to a polarity that is opposite a polarity of the developer which is electrically charged to a positive polarity or a negative polarity, based on a potential difference between a developing part and the image carrier. The supply amount increasing unit increases an amount of supply of the oil-impregnated particles to the image carrier by adjusting the potential of the image carrier, while a developing operation is not being performed by the developing unit.
