Claim 0:
1. A lubricant applying device comprising:
a rotatable applicator to apply lubricant to a member to be coated;
a solid lubricant source having a contact surface to contact the applicator to supply the lubricant to the applicator;
an urging member to urge the lubricant source to contact the applicator; and
a guide member to restrict an urging of the lubricant source along a displacement direction,
wherein the contact surface of the lubricant source includes a contact area having an arcuate shape at least partially conforming to an outer circumference of the applicator, and
wherein, in a transverse cross-section of the lubricant applying device that is taken orthogonally to a rotation axis of the applicator, the contact area of the lubricant source has a geometric center, the geometric center of the contact area of the lubricant source to move along the rotational direction of the applicator from an upstream side of a reference line that extends from the contact surface of the lubricant source to the rotation axis of the applicator in a direction parallel to the displacement direction of the guide member to a downstream side of the reference line based on the lubricant source being consumed.
