Electro-conductive belt, fabrication method thereof, and image forming device

摘要

There is provided an electro-conductive belt fabrication method having a drying step of forming a dry film, which includes applying a conductive-particle dispersion to the inside face of a circular tube, rotating the tube about its axis and forming a dispersion layer at a surface of the tube, and drying the dispersion layer until an amount of solvent in the dispersion layer reaches a predetermined residual amount; a resin material leaching step, which includes applying a liquid containing the dissolved or swollen resin material to a surface of the dry film, and leaching the resin material to a predetermined depth in the surface of the dry film; and a heating step that includes one of heating the resultant dry film and drying the dry film, and changing the precursor in the dry film to the predetermined resin material.

主权项

1. An electro-conductive belt fabrication method comprising:
a drying step of forming a dry film, including
applying a dispersion, in which conductive particles are dispersed in a solvent solution of a resin material, to an inner peripheral face of a circular tube,rotating the circular tube about an axis of the circular tube and forming a dispersion layer on the inner peripheral face at a surface of the circular tube, anddrying the dispersion layer until an amount of solvent in the dispersion layer reaches a predetermined residual amount; a resin material leaching step, including
applying a liquid in which the resin material is dissolved or swollen to a surface of the dry film obtained by the drying step, andleaching the resin material to a predetermined depth in the surface of the dry film; and a heating step, including
heating the dry film into which the resin material has been leached to the predetermined depth by the resin material leaching step and drying the dry film.
