Embodiment 1

[0202] In Example 1, the amount of zinc on the surface of the image bearing member corresponding to the area of ​​the image occupancy rate of 0% was adjusted to 2.5 atomic% and the amount of boron was adjusted to 30.2 atomic %. The amount of zinc on the surface of the image bearing member corresponding to the area of ​​100% of the image occupancy rate was adjusted to 2.1 atomic% and the amount of boron was adjusted to 23.9 atomic %.

Embodiment 2

[0204] In Example 2, the amount of zinc on the surface of the image bearing member corresponding to an area of ​​0% of the image occupancy rate was adjusted to 2.3 atomic% and the amount of boron was adjusted to 12.5 atomic %. The amount of zinc on the surface of the image bearing member corresponding to the area where the image occupancy rate was 100% was adjusted to 1.8 atomic% and the amount of boron was adjusted to 7.8 atomic %.

Embodiment 3

[0206] In Example 3, the amount of zinc on the surface of the image bearing member corresponding to the area of ​​0% of the image occupancy rate was adjusted to 1.0 atomic% and the amount of boron was adjusted to 3.3 atomic %. The amount of zinc on the surface of the image bearing member for the area where the image occupancy rate is 100% was adjusted to 0.4 atomic% and the amount of boron was adjusted to 1.2 atomic %.

Abstract

The invention relates to a protecting agent-supplying device, a process cartridge, an image forming apparatus and an image forming method. The protecting agent-supplying device which supplies, to an image bearing member, an image bearing member-protecting agent for protecting the image bearing member, wherein the image bearing member-protecting agent contains at least a fatty acid zinc salt and boron nitride, and wherein the protecting agent-supplying device supplies the image bearing member-protecting agent to the image bearing member so that the amount of zinc (Zn) present on a surface of the image bearing member satisfies the relation 0.4!<=Zn!<=2.5 (Atomic %) and the amount of boron (B) present on the surface of the image bearing member satisfies the relation 0.2!<=B!<=30.2 (Atomic %).

Description

Technical field [0001] The present invention relates to a protective agent supply device, a process cartridge containing the protective agent supply device, an image forming apparatus containing the protective agent supply device or a process cartridge, and a protective agent supply device, a process cartridge or an image forming apparatus In an image forming method, the protective agent supply device supplies an image-bearing member protective agent for protecting an image-bearing member in an image forming apparatus such as a copying machine, a facsimile machine, and a printer. Background technique [0002] In an image forming apparatus (such as a copying machine, a facsimile machine, and a printer) having an image bearing member (such as a photoconductor made of, for example, a photoconductive compound), the image bearing member is rotated and sequentially performed, for example, a charging step, an exposure step, and a development step , Transfer step and fixing step to form ...
