Claim 11:
12. An image forming apparatus comprising:
a member to be coated;
a lubricant applying device comprising:
a rotatable applicator to apply lubricant to the member to be coated; and
a solid lubricant source having a contact surface that faces the applicator,
wherein the contact surface includes a contact area that is in contact with the applicator to supply the lubricant to the applicator, and
wherein the contact area has a geometric center in a transverse cross section of the lubricant applying device that is taken orthogonally to a rotation axis of the applicator, the geometric center to move along a rotational direction of the applicator based on the lubricant source being consumed;

an urging member to urge the lubricant source to contact the applicator; and
a guide member to guide the lubricant source in an urging direction of the urging member,
wherein a reference line extends from the contact surface of the lubricant source to the rotation axis of the applicator and parallel to the urging direction of the urging member in the transverse cross section, the geometric center of the contact area of the lubricant source to move from an upstream side of the reference line to a downstream side of the reference line based on the lubricant source being consumed by a rotation of the applicator.
