In a cycolor type color video printer including a roller type developing apparatus for transcribing an exposed color image of a cylith film onto a receiver paper by means of pressing power provided thereby, said developing apparatus comprising:

• a pair of side plates mounted on a base of said color video printer and spaced apart from each other, said side plates each provided with a mounting hole;
• rotary pressing means rotatably supported between said side plates, said rotary pressing means provided with a clearance for allowing said cylith film and said receiver paper to pass therethrough at the same time, and said rotary pressing means comprising an upper pressing roller provided with a pair of flanges, one at each end thereof, and a cylindrical lower pressing roller contacting with said flanges of the upper pressing roller at both ends thereof, thereby providing said clearance between said upper and lower pressing rollers;
• upper and lower support bearings vertically mounted in each said mounting hole of said side plate and connected to respective end shafts of said rotary pressing means, respectively, and each adapted for supporting said rotary pressing means rotatably;
• and
• a pressure controlling means for controlling said clearance in order to control the pressure for said rotary pressing means.
