摘要： A pigment ink is provided which has good ink reliability and storage stability and can achieve superior scratch resistance of images at such a level that coloring materials are hardly scraped off even when images are scratched with finger nails under application of such strong pressure as to scratch a recording medium at its non-recorded areas. The pigment ink contains a pigment, a modified siloxane compound having a specific structure, and a polymer whose acid value and hydrogen bond parameter (δh) are specified.

摘要： To enable a bunch of sheets to be reliably discharged to a stack tray, also in the case where weight of the bunch of sheets formed on a processing tray is large, upon receiving a printing command, a main body control section checks information on an ink discharge amount in printing on a sheet, the number of sheets, sheet type and printing mode (two-side/one-side). By this means, the section recognizes weight of the bunch of sheets formed on the processing tray, and when determining that the weight is heavier than predetermined weight, deceases an upper limit value of the number of sheets of a bunch of sheets formed at a time to report to a user.
