Abstract:
An image forming apparatus using a developing liquid consisting of a dielectric carrier liquid and toner dispersed in said carrier liquid, and causing said developing liquid to form a layer on a developer carrier and contact an image carrier on which a latent image is electrostatically formed to thereby develop said latent image, said image forming apparatus comprising:said developer carrier implemented by a hollow tubular member;a drive roller rotatably disposed in a bore of said developer carrier for causing said developer carrier to rotate; anda pressing member pressed against an outer periphery of said developer carrier for exerting a pressure or said drive roller via said developer carrier,wherein a frictional force Fa acting between an inner periphery of said developer carrier and an outer periphery of said drive roller while said drive roller is in rotation is selected to be greater than a frictional force Fb acting between the outer periphery of said developer carrier and said pressing member.
