摘要：
A process cartridge including an image bearing member; a lubricant applicator, which includes a lubricant application member configured to apply a solid lubricant to the surface of the image bearing member; and a smoothing member configured to smooth the applied solid lubricant, and at least one of a charging device, a developing device and a cleaning device, wherein the amount of the solid lubricant present on a portion of surface of the image bearing member, which is located between the lubricant application member and the smoothing blade, is from 0.11 to 1.2 mg/m2. The smoothing member is preferably a blade having a JIS-A hardness of not less than 79°. The process cartridge is preferably assembled by a method including setting the lubricant smoothing member, the lubricant and the lubricant application member to a housing of the process cartridge; and then setting the image bearing member to the housing.
