Claim:
1. A printer comprising: a print executing unit including: a controller configured to control the print executing unit to perform a multi-pass printing for printing a target image on the sheet with a plurality of pass processes, the plurality of pass processes forming a plurality of partial images respectively, two partial images formed with successive two pass processes overlapping partially, and K number of active nozzles consecutively arranged being selected from the plurality of nozzles for each of the plurality of pass processes, wherein the controller is further configured to control the print executing unit to perform: an (a)-print process in which the conveying mechanism conveys the sheet and at least two pass processes are executed with Ka number of active nozzles, a (b)-print process in which the conveying mechanism conveys the sheet and executed with Kb number of active nozzles, the (b)-print process being executed after the (a2)-pass process, the Kb number of active nozzles including a third downstream segment including a most-downstream nozzle of the Kb number of active nozzles in the conveying direction, and dot recording rates of active nozzles included in the third downstream segment decreasing from a most-upstream nozzle of the third downstream segment toward the most-downstream nozzle of the Kb number of active nozzles.
