Abstract
A method of coating a photoconductive element for an electrophotographic image forming-apparatus and an apparatus therefore are disclosed. A plurality of cylindrical bodies are immersed in a bath, which stores a coating liquid, at the same time and then lifted out of the bath. As a result, a photoconductive film is formed on each cylindrical body.
Claims7
In a method of immersing a plurality of cylindrical bodies in a bath, which stores a coating liquid, at the same time and then lifting said plurality of cylindrical bodies to thereby form a film on each cylindrical body, said bath comprises a plurality of chambers each being positioned beneath one of said plurality of cylindrical bodies and storing said coating liquid,
- the plurality of cylindrical bodies are positioned in a space that is closed at a top, surrounded by a flexible hood at sides, and open at a bottom for discharging vapor of a solvent, which is contained in the coating liquid, produced during immersion or drying to touch,
- the plurality of cylindrical bodies are immersed in the coating liquid in the bath while being confined in said flexible hood,
- the plurality of cylindrical bodies and said flexible hood are lifted together when said plurality of cylindrical bodies are lifted at a constant speed or a varying speed, and
- the bottom of said flexible hood is positioned, when the plurality of cylindrical bodies are brought to a stop after a lift, at a level coincident with or lower than a level of bottoms of said plurality of cylindrical bodies.
