Process cartridge and image forming apparatus

An image forming apparatus, comprising:

• a process cartridge, including
• an image bearing member, which is rotatable and is configured to bear a developer image formed of developer;
• a developer bearing member, which is configured to be rotatable in a state in contact with the image bearing member in order to supply the developer to the image bearing member, for forming the developer image on a surface of the image bearing member;
• and
• a cleaning member disposed in contact with the image bearing member and configured to clean the surface of the image bearing member by scraping off the developer remaining on the surface of the image bearing member after the developer image is transferred from the image bearing member,
• wherein a fixation layer, including at least one of an organosilicon polymer and inorganic particles, is provided on a surface of the developer borne on the developer bearing member, and a fixation percentage of the fixation layer on the surface of the developer is 85% or greater, and
• wherein the image bearing member and the developer bearing member are rotationally driven such that, the surface of the image bearing member and a surface of the developer bearing member move in opposite directions from each other at a contact portion where the image bearing member and the developer bearing member are in contact with each other;
• and
• a fixing device configured to fix the developer image to a recording medium.
