Abstract: A wet developer for use in electrophotography which consists of a carrier liquid having electric resistance of 10.sup.9 .OMEGA. . cm or more and dielectric constant of less than 3 and containing colored particles with a particle size of about 0.1 .about. 10 .mu., said particles being substantially insoluble in said carrier liquid, possessed of properties of solid matter and showing a distinct polarity within said carrier liquid, coupled with adhesive suspended particles with a particle size of about 0.01 .about. 10 .mu. which show the same polarity as said colored particles.
