Abstract:
A developing apparatus for developing an electrostatic latent image formed on an image carrying member, comprising:a developer carrying member for holding a developer and introducing the developer into a developing area, the developer carrying member arranged opposite to the image carrying member at a distance;a voltage applying device for applying an AC voltage composed of a rectangular wave to the developer carrying member; anda resistor inserted between the voltage applying device and the developer carrying member, the resistor having a resistance value of 10.sup.3 to 10.sup.7.OMEGA.:the AC voltage having a first time period during which a first voltage is exerted in a first direction in which the developer is fed to the image carrying member and a second time period during which a second voltage is exerted in a second direction in which the developer is returned to the developer carrying member, the first time period being shorter than the second time period.
