Title:
CORE-SHEATH CONJUGATED TYPE ELECTROCONDUCTIVE FIBER
Document Type and Number:
Japanese Patent JP2003020523
Kind Code:
A
Abstract:
To obtain a core-sheath conjugated type electroconductive fiber which has a stable specific resistance value to change in temperature and humidity in a long-term use and with which a stable and excellent image can be obtained without causing a dispersion of specific resistance value between fibers when used as a brush for contact charging.
This core-sheath conjugated type electroconductive fiber contains electroconductive fine particles in a sheath part and the ratio (ρb/ρa) of specific resistance values ρb and ρa before and after hot-water treatment of ≤102.
