摘要： A process cartridge (100; 507; 712) including an image bearing member (10; 310; 502; 701); a lubricant applicator (20; 160; 531; 631; 707), which includes a lubricant application member (23; 161; 533; 771) configured to apply a solid lubricant (22; 162; 534; 772) to the surface of the image bearing member; and a smoothing member (21; 532; 774) configured to smooth the applied solid lubricant, and at least one of a charging device (30; 509; 702), a developing device (50; 526; 706) and a cleaning device (40; 531; 631; 707), 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/m 2 . 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 (110; 410) of the process cartridge; and then setting the image bearing member to the housing.

摘要： A lubricant supply device includes a solid lubricant, a supply member contacting and rubbing the solid lubricant and thereby scraping a lubricant off the solid lubricant and supplying the lubricant to a lubricant supplying target, and a pressing mechanism pressing the solid lubricant against the supply member. The pressing mechanism includes a biasing device, and a plurality of pressing members receiving a biasing force of the biasing device and thereby pressing places of the solid lubricant at symmetrical positions with respect to a center of a contact part of the solid lubricant contacting the supply member, respectively.
