ABSTRACT:
A developing apparatus has a toner carrier having a horizontal portion disposed near the surface of a photoconductive member on which an electrostatic latent image is formed, and an inclined portion having one end portion embedded in a toner. The horizontal and inclined portions having strip electrodes thereon. A voltage circuit applies to the strip electrodes potentials, which change in a stepwise manner as a time function, so as to form electric fields shifting from the inclined portion to the horizontal portion. An opposed electrode is disposed to oppose the inclined portion. A voltage, which is half the maximum value of the potentials applied to the strip electrodes of the toner carrier, is applied to the opposed electrode.
