Abstract
A wet developing apparatus of the type which is provided with a rotary member for developing an electrostatic latent image carried on a latent image carrier wherein said member supplies a liquid developer to the carrier and recovers residual liquid developer from the carrier by use of an elastic deformation of the rotary member, which wet developing apparatus is characterized in that the relative position between said rotary member and the latent image carrier is determined so that the width of said rotary member, measured along the axial direction in which said rotary member comes in pressure contact with said latent image carrier, is within the range of from the maximum width of the area in which an electrostatic latent image can be carried by said carrier to the total width of said carrier.

A wet developing apparatus of the type which is provided with a rotary member for developing an electrostatic latent image carried on a latent image carrier, said rotary member being elastically deformable and being disposed in pressure contact with said carrier while supplying liquid developer thereto and while recovering residual liquid developer therefrom, said apparatus being characterized in that said rotary member is an elastic roller comprising a porous elastic material overlaid on the circumference of the roller shaft, and in that the relative position between said rotary member and said latent image carrier is determined so that the width of said rotary member, measured along the axial direction in which said rotary member comes in pressure contact with said latent image carrier, is within the range of from the maximum width of the area in which an electrostatic latent image can be carried by said carrier to the total width of said carrier.
A wet developing apparatus of the type which is provided with a rotary member for developing an electrostatic latent image carried on a latent image carrier, said rotary member being elastically deformable and being disposed in pressure contact with said carrier while supplying a liquid developer thereto and while recovering residual liquid developer therefrom, said apparatus being characterized in that said rotary member has rollers provided at both ends thereof to form means for controlling the degree of pressure contact between said rotary member and said latent image carrier, said rollers having openings therein through which liquid passes away, and wherein the relative position between said rotary member and said latent image carrier is determined so that the width of said rotary member, measured along the axial direction in which said rotary member comes in pressure contact with said latent image carrier, is within the range of from the maximum width of the area in which an electrostatic latent image can be carried by said carrier to the total width of said carrier.
