METHOD AND APPARATUS FOR APPLYING COATING LIQUID TO CYLINDRICAL SUBSTRATE, METHOD FOR MANUFACTURING ELECTROPHOTOGRAPHIC PHOTORECEPTOR, AND ELECTROPHOTOGRAPHIC PHOTORECEPTOR MANUFACTURED THEREBY

摘要

PROBLEM TO BE SOLVED: To efficiently form a coating film having uniform thickness on a cylindrical substrate by restraining the generation of a joint by simple control when a coating roll is parted from the cylindrical substrate. SOLUTION: A coating liquid 3 is supplied to the coating roll 2 from a coating liquid supplying means 4 through a metering roll 13. The coating liquid 3-supplied coating roll 2 and the cylindrical substrate 5 which is arranged to be close to the coating roll 2 or be abutted on the coating roll 2, are rotated separately so that the coating liquid 3 is transferred to the cylindrical substrate 5 from the coating roll 2. After the cylindrical substrate 5 is rotated by the predetermined number of times, the circumferential speed V1 of one of the coating roll 2 and the cylindrical substrate 5 is controlled to be higher than the circumferential speed V2 of the other when the coating roll 2 is separated from the cylindrical substrate 5.
