Abstract
A developing apparatus for bringing a film into contact with a frame portion which defines a developing chamber in such a manner that a surface of the film formed an electrostatic latent image is opposed to a developing electrode disposed in the developing chamber, and for developing the film under a liquid developer supplied to the developing chamber while applying a bias voltage to the developing electrode. The developing apparatus interrupts the application of the bias voltage to the developing electrode at the time of the contact. Consequently, discharge between the film and the developing electrode can be prevented at the time of the contact.
