Abstract:
A developing apparatus for developing an electrostatic latent image formed on an image carrying member, comprising:a developer carrying member arranged opposite to the image carrying member and holding a developer; anda voltage applying device applying an AC voltage to said developer carrying member, whereinsaid 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,a voltage waveform of said AC voltage comprising a first straight line portion and a second straight line portion while changing from said first peak potential to said second peak potential,the first straight line portion existing between the first peak potential and the second straight line portion, anda slope of the voltage waveform of said first straight line portion being gentler than a slope of the voltage waveform of said second straight line portion.
