<P>PROBLEM TO BE SOLVED: To provide printing equipment using sticky ink which can suppress a rise in temperature of ink in a development apparatus by a simple and inexpensive constitution, and which can enhance image quality. <P>SOLUTION: In this development apparatus 16A, the ink in an ink reservoir 29 is supplied to an ink fountain roller 28 and an ink supply roller 27, and distributed to inking rollers 25 and 26 which are brought into contact with a plate drum 13. A cooling roller 31 with a hollow structure is brought into contact with the roller 27, and cooling rollers 32 and 33 continue to the cooling roller 31 in such a manner as to be serially and rotatably in contact above the apparatus. The rise of the temperature of the ink is suppressed by the cooling function of a group of the cooling rollers 31, 32 and 33. A fan 34 for blowing air outside the development apparatus on the group of the cooling rollers is provided on the upper right side of a development casing 24. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
