Conductive belt, method of producing same, and image-forming apparatus having same
摘要：
A method of producing a conductive belt composed of a base resin containing polybutylene naphthalate resin at not less than 50 mass % nor more than 100 mass % and 1 to 3 mass % of carbon nano-fibers having a DBP oil absorption amount at not less than 150 ml/100 g. The method includes the steps of forming a conductive master batch by mixing the carbon nano-fibers with resin for use in a master batch containing the polybutylene naphthalate resin; mixing the obtained conductive master batch and resin for blending use containing the polybutylene naphthalate resin and not containing the carbon nano-fibers with each other in an unmelted state by setting a mixing mass ratio of the conductive master batch smaller than that of the resin for blending use; and meltingly molding an obtained mixture by an extrusion molder.
