PROBLEM TO BE SOLVED: To provide a process cartridge that is filled with a toner at high density but can provide stability of images with high print quality.SOLUTION: A process cartridge stores, in a toner container 24, a toner having a uniaxial yield stress of 2.0 kPa or more and 4.5 kPa or less at the time of a maximum compaction stress of 10.0 kPa and a total energy measured after compaction of 70 mJ or more and 95 mJ or less, at a packing density of 0.70 g/cmor more.SELECTED DRAWING: Figure 2 |
