Claims15
A protective agent for application onto a surface of an image bearing member of an image forming apparatus, the protective agent comprising:
- a hydrophobic organic compound (A);
- an inorganic fine particle (B);
- and
- an inorganic lubricant (C),
- wherein the inorganic lubricant (C) constitutes 50% or less of the protective agent.
A protective layer setting unit for applying a protective agent onto a surface of an image bearing member of an image forming apparatus, comprising:
- an application unit to apply the protective agent onto a surface of the image bearing member, the protective agent comprising:
- a hydrophobic organic compound (A);
- an inorganic fine particle (B);
- and
- an inorganic lubricant (C),
- wherein the inorganic lubricant (C) constitutes 50% or less of the protective agent.
An image forming apparatus, comprising:
- an image bearing member to bear a toner image thereon;
- a transfer unit to transfer the toner image from the image bearing member to a transfer medium;
- and
- a protective layer setting unit for applying a protective agent onto a surface of the image bearing member after transferring the toner image to the transfer medium, comprising:
- an application unit to apply the protective agent onto a surface of the image bearing member, the protective agent comprising:
- a hydrophobic organic compound (A);
- an inorganic fine particle (B);
- and
- an inorganic lubricant (C),
- wherein the inorganic lubricant (C) constitutes 50% or less of the protective agent.
A process cartridge comprising:
- an image bearing member to bear a toner image thereon;
- and
- a protective layer setting unit for applying a protective agent onto a surface of the image bearing member, comprising:
- an application unit to apply the protective agent onto a surface of the image bearing member, the protective agent comprising:
- a hydrophobic organic compound (A);
- an inorganic fine particle (B);
- and
- an inorganic lubricant (C),
- wherein the inorganic lubricant (C) constitutes 50% or less of the protective agent and the image bearing member and the protective layer setting unit being integrated in a single assembly.
