2 more elements
A protective layer forming device comprising:
- a unit configured to apply an image-bearing member protecting agent onto a surface of an image bearing member so as to form a protective layer,
- wherein the image-bearing member protecting agent comprises:
- a hydrophobic organic compound (A);
- an inorganic lubricant (B);
- and
- inorganic fine particles (C),
- wherein each of the inorganic fine particles (C) has a specific surface area of 2.0 m2/g to 6.5 m2/g.
4 more elements
An image forming method comprising:
- forming a latent electrostatic image on an image bearing member;
- developing the latent electrostatic image using a toner so as to form a visible image;
- transferring the visible image formed on the image bearing member to a transfer medium;
- and
- applying an image-bearing member protecting agent onto a surface of the image bearing member, from which the visible image has been transferred to the transfer medium, so as to form a protective layer thereon,
- wherein the image-bearing member protecting agent comprises:
- a hydrophobic organic compound (A);
- an inorganic lubricant (B);
- and
- inorganic fine particles (C),
- wherein each of the inorganic fine particles (C) has a specific surface area of 2.0 m2/g to 6.5 m2/g.
