摘要： A liquid image forming system including a photosensitive body on which an electrostatic latent image is formed, a developing roller which forms a contact nip with the photosensitive body, and a metering member which is closely adhered to the developing roller and regulates the developing agent to a predetermined thickness. The system includes an intermediate transfer medium onto which the image formed on the photosensitive body is transferred via a first transfer nip, and a transfer roller which forms a second transfer nip with the transfer medium. A pressure applied to the contact nip is less than 1.2 times a pressure of the metering member on the developing roller. A pressure applied to the first transfer nip is less than 1.2 times the pressure applied to the contact nip. A pressure applied to the second transfer nip is less than 1.5 times the pressure applied to the first transfer nip.

The elastic rubber layer forms a squeegee nip by contacting a photoreceptor web, thereby to make a toner of the excess developer, which is developed in an area for an electrostatic latent image of the photoreceptor web, into a thin film in the area for electrostatic latent image and to squeeze the remaining carrier. The roughness (Ra) of a surface of the elastic rubber layer satisfies the condition, 1.5 &mgr;m≦Ra≦2.5 &mgr;m. Further ,a criss-cross grove pattern is formed on the surface of the squeegee roller so as to guide the excess developer liquid
