Abstract
An example lubricant applying device includes a rotatable applicator, a solid lubricant source to supply 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. In a transverse cross section of the lubricant applying device that is taken orthogonally to a rotation axis of the applicator, a reference line extends from a 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. In the transverse cross section, the lubricant source has a width that is substantially orthogonal to the displacement direction. The lubricant source is positioned to offset a widthwise center of the lubricant source to a downstream side of the reference line, in the rotational direction of the applicator.
