PURPOSE:To prevent uneven charging and obtain a good image constantly by molding a compsn. contg. a specific resin component and a conductive carbon black. CONSTITUTION:A resin component contg. a copolycarbonate resin having structural units of formula I wherein A is a 1-10C linear, branched, or cyclic alkylidene group, an aryl-substd. alkylidene group, an arylenedialkylidene group,-0-,-S-,-CO-,-SO-, or -S02-; and R1 to R4 are each H, halogen, 1-4C alkyl, or alkenyl and 0.1-50wt.% structural units of formula II wherein R5 is 2-6C alkylene or alkylidene; R6 and R7 are each 1-3C alkyl or (substd.) phenyl; and n is 1-200 and 1-40wt.% thermally reversible arom. vinyl resin is mixed with a conductive carbon black in an amt. of 0.1-30 pts.wt. based on 100 pts.wt. the resulting compsn. The compsn. is molded to give the title member. |
