Abstract: PURPOSE: A squeeze roller for a wet electronic photograph type printer is provided to enhance the squeezing efficiency by forming a pattern formed a groove of about 45 degree on the surface of the squeeze roller. The roughness of the squeeze roller is preferably about 2.0 micrometer. CONSTITUTION: The squeeze roller for a wet electronic photograph type printer includes following units. An elastic rubber layer(44) is formed with a predetermined thickness to the outside surface of a steel core(42) of the squeeze roller(40). The elastic rubber layer(44) is contacted with a photosensitive medium(50), thereby forming a squeeze nip. There is a need of guiding the flow of the developing solution in order to be discharged an excessive developing solution squeezed from the squeeze nip. Accordingly, a groove pattern(GP) having an inclination of about 45 degree to the shaft direction of the squeeze roller(40) is processed at the surface of the elastic rubber layer(44). The angle of the groove is optimum in order to be guided easily the excessive developing solution.
