ELECTROPHOTOGRAPHIC DEVELOPING APPARATUS

摘要

An apparatus for developing an electrophotographic film carrying an electrostatic latent image, wherein said film is supported by film supporting means in a substantially vertical plane, and is opposed to an aperture of a developing chamber which has an outlet formed at a lower portion thereof and an air introducing opening formed at an upper portion thereof. Engaging means causes the film to be engaged over and close to said aperture by relative movement between the chamber and the film so as to form a space within the chamber capable of receiving a predetermined volume of liquid developer from a developer supply means. After the liquid developer is kept in the space for a predetermined time for development of the film, developer discharge means discharges the developer from the space through the outlet under the control of control means, and air is introduced into said space from said air introducing opening as the level of the liquid developer falls as the developer is discharged from the space.
