Abstract

Official abstract text for this publication.

A protecting agent-supplying device including: a rotation member configured to rotate in a certain direction; an image bearing member-protecting agent containing a fatty acid metal salt and an inorganic lubricant, and being in the form of a solid, wherein the agent is scraped off by the rotation of the rotation member, supplied to an image bearing member for protection thereof, and disposed to have a surface facing the rotation member, which surface has a width G in a direction along the certain direction, and wherein the position X (a center of the width G) is located upstream in the direction along the certain direction from the position Y (a line of intersection between the surface facing and a line extended from the rotational center of the rotation member perpendicular to the surface facing), and a distance d between these positions satisfies a formula 0<d≦G/2.
