Abstract
A developing apparatus for an electrophotographic copying machine includes a developer carrier disposed in opposing relationship with a member on which an electrostatic latent image is formed. A vibrator comprising a single sheet piezoelectric element which is adapted to undergo vibrational oscillation in the direction of its thickness or a plurality of such elements bonded together is closely engaged with the developer carrier to cause the developer to fly toward the latent image carrying member.
