ABSTRACT:
The present invention provides a transfer member containing a polyimide resin and carbon black. The carbon black has a pH value of no more than 5 and a volatile component of at least 3.5%, and the content of carbon black is 22 to 30 parts by weight relative to 100 parts by weight of the polyimide resin. The invention also provides a method for manufacturing a transfer member comprising the steps of: dividing a poly(amic acid) resin solution containing carbon black into plural portions, and mixing the divided solutions by allowed the solutions to collide with each other at a pressure of at least 150 MPa; and forming a transfer member containing the polyimide resin using the poly(amic acid) resin solution, which has the carbon black mixed therein. The invention further provides an image forming apparatus using the transfer member above.
