PROBLEM TO BE SOLVED: To enable uniform and high-density static charge application and cleaning in the case of using a static charge brush and a cleaner brush by stably producing a high-density pile using a conductive combined filament yarn with different shrinkage percentage and achieve high picture image of a dry copier, facsimile, printer, etc., of electrophotographic recording type. SOLUTION: The combined filament yarn with different shrinkage percentage is produced by blending (A) 30-80wt.% thermoplastic fiber and (B) 20-70wt.% thermoplastic fiber having a boiling water shrinkage higher than that of the thermoplastic fiber A by 10-40%. The invention provides a conductive combined filament yarn with different shrinkage percentage produced by using the thermoplastic fiber A containing 10-40wt.% conductive carbon based on the total weight of the fiber A, and a static charge brush and a cleaner brush produced by using the conductive combined filament yarn with different shrinkage percentage.
