Title:
PROTECTIVE LAYER FORMING DEVICE, PROTECTIVE AGENT BAR, IMAGE FORMING APPARATUS, AND PROCESS CARTRIDGE
Document Type and Number:
Japanese Patent JP2008096723
Kind Code:
A
Abstract:

To provide a protective layer forming device capable of forming a protective layer on an image carrier in an appropriate quantity, maintaining the protective effect of a protective agent and, at the same time, reducing a wasteful consumption of the protective agent.

The protective layer forming device 2 has a means for supplying the protective agent to the image carrier 1 by means of a protective agent bar 21 and a protective agent supply member 22 of a brush form. The device 2 supplies the protective agent to the image carrier so that the total amount of protective agent contained in waste toner relative to the consumption of all the protective agent supplied to the image carrier is 20% or less. In the protective layer forming device 2, the brush 22a of the protective agent supply member 22 for applying the protective agent is brought into contact with the protective agent bar 21, thereby attaching the protective agent of an irregular shape to the leading end of the brush and supplying this protective agent to the image carrier. Accordingly, the quantity of protective agent supplied to the surface of the image carrier is properly kept and the protective layer is formed from the protective agent of irregular shape. This reduces wasteful consumption of the protective agent while maintaining the protective effect of the protective agent.
