ABSTRACT:
In an image forming apparatus having a liquid developing device, a thin layer of dense and viscous developing liquid is formed on a developer carrier and brought into contact with a latent image electrostatically formed on the surface of an image carrier in order to develop it. A preselected electric field is formed between the developer carrier and a device for regulating the thickness of the above layer, providing a dense layer with a uniform high toner content and an excess liquid surface layer. The excess liquid surface layer, formed with the developing liquid layer, is removed by a developing layer removing device. With this configuration, the apparatus ensures images free from irregularity.
