[PROBLEMS] To suppress the failure of the coating when starting the application of the coating solution. A slit die 26 for discharging the coating liquid L _T from the discharge port 26A on the outer circumferential surface of the substrate 14 A1 A photoreceptor manufacturing apparatus 10 includes a lid member which forms a cleaning chamber 64 when it covers the discharge port 26A at least I have a 62, with the introduction unit 60 to be discharged with introducing a cleaning liquid L _S in the cleaning chamber 64, and a control unit 50. Here, control is performed to discharge the application liquid L _T into the wash chamber 64 from the discharge port 26A prior introduction unit 60 to stop, the control unit 50, to discharge the coating liquid L _T into the wash chamber 64 . As a result, the coating liquid L _T that generate dilute the cleaning solution L _S in the discharge port 26A near is discharged, reduced concentration of the coating solution L _T of the discharge port 26A within is suppressed, the application of the coating solution L _T the next It is possible to prevent failure of the coating at the start.
