Title:
プロセスカートリッジおよび電子写真装置
Document Type and Number:
Japanese Patent JP7337650
Kind Code:
B2
Abstract:
There is provided a process cartridge detachably attachable to a main body of an electrophotographic apparatus, the process cartridge including: an electrophotographic photosensitive member and a charging member, in which when average local potential differences of calculated lengths in the electrophotographic photosensitive member is calculated based on a specific method, a maximum value of the average local potential difference is 2 V or more, the charging member includes a support and an electro-conductive layer, the electro-conductive layer has a matrix and domains dispersed in the matrix, a volume resistivity ρM of the matrix is at least 1.00×105 times a volume resistivity ρD of the domain, and a specific calculated length SCP [μm] and a specific value relating a distance between the domains Dms [μm] satisfy SCP≥3×Dms.
