Abstract

A line sensor includes plural sensor chips and a gap between adjacent two sensor chips. In a test pattern image, a thin line is formed by ink ejected from a nozzle. Further, the line sensor scans the test pattern image on a sheet slanted from a transportation direction of the sheet and generates a test pattern scanned image. An ejection malfunction determination unit determines densities at at least two secondary-scanning-directional positions at a primary-scanning-directional position corresponding to each nozzle in the test pattern scanned image, and determines whether the nozzle is an ejection malfunction nozzle or not on the basis of the determined densities. Here, a slant angle of the sheet is set such that a primary-scanning-directional distance between two positions in the test pattern image corresponding to the two secondary-scanning-directional positions is larger than an arrangement interval of sensor pixels in the sensor chip.
