ABSTRACT:
In an ink jet apparatus of the type which includes an ink jet head having a plurality of ejection openings for ejecting ink and adapted to print by ejecting ink from the ejection openings onto a print material, a carrying device carrying the ink jet head and provided such that it is movable in main scanning directions for the print material, and a cleaning device for cleaning that surface of the ink jet head on which the ejection openings are provided by abutting against this surface as the carrying device moves along, the cleaning device is a cleaning blade adapted to generate different abutting forces with respect to that surface of the ink jet head on which the ejection openings are provided. With this ink jet apparatus, it is possible to reduce the amount of ink left unwiped on the ejection surfaces of various types of ink jet heads, thereby realizing a high-quality-printing ink jet apparatus that is free from defective ink ejection, color mixing or the like.
