Abstract
A process for producing an electrophotographic photosensitive member has a layer. The process has the step of forming the layer by the use of a dispersion obtained by ejecting a pressurized fluid from an orifice into a hollow member having a diameter larger than the diameter of the orifice, to disperse a material to be dispersed. The fluid is ejected in substantially an unatomized state.
Claims17
A process for producing an electrophotographic member having a layer on a conductive support comprising:
- (a) ejecting a pressurized fluid in substantially an unatomized state from an orifice into a hollow member, said hollow member having a diameter (i) 10 mm or less and (ii) 3 to 50 times the diameter of the orifice, to form a dispersion of a material;
- and
- (b) coating said dispersion on said conductive support to form said layer.
