CLEANING BLADE, CLEANING DEVICE, PROCESS CARTRIDGE, AND IMAGE FORMING APPARATUS

摘要

The objective of the present invention is to provide a cleaning blade capable of preventing the generation of a scratch. To solve the objective, the cleaning blade of the present invention comprises the dynamic-ultra-micro hardness of a part which touches at least a cleaning object member is 0.25 or more to 0.65 or less, and a member which has an index K of 15 or more in a flowing formula (1). (formula (1)) index K=[23°C break elongation (%)]×[10°C repulsion elasticity (%)]×(-1)×[tanδ peak temperature (°C)]÷[Young′s modulus (MPa)]÷1000.
