ABSTRACT:
A developing apparatus according to the present invention for developing an electrostatic latent image formed on an image carrying member has a developer carrying member arranged opposite to an image carrying member and holding a developer, and a voltage applying device applying an AC voltage to the developer carrying member, wherein the AC voltage has a first peak potential and a second peak potential, the first peak potential being a peak potential on the side of development for supplying the developer to the image carrying member, the second peak potential being a peak potential on the side of recovery for returning the developer to the developer carrying member, and a voltage waveform of the AC voltage always has two straight line portions which differ in slopes while changing from the first peak potential to the second peak potential and/or from the second peak potential to the first peak potential.
