Abstract:
1. An electrostatic painting method for electrostatically painting an opening/closing object provided in an object to be painted by a painting device while opening and closing the opening/closing object by the opening/closing device, comprising; applying high voltage to the opening/closing device by a high-voltage applying device to create an electrostatic field around the opening/closing device; detecting an amount of discharge current discharged between the opening/closing device and the opening/closing object by a discharge current detecting device; performing electrostatic painting while determining a positional relationship between the opening/closing object and the opening/closing device based on the amount of discharge current detected by the discharge current detecting device, comparing (a) the amount of discharge current to a first current amount while the opening/closing device is moving relative to the opening/closing object, or (b) the amount of discharge current to a first current amount or to a range between a second current amount that is smaller than the first current amount and a third current amount that is smaller than the second current amount while the opening/closing device is engaged with the opening/closing object; wherein the first current amount, second current amount, and third current amount are predetermined threshold values for determining whether the positional relationship is normal or abnormal.
