PROBLEM TO BE SOLVED: To provide a fluid consumption measuring device which can measure fluid consumptions for respective types of fluids even if a plurality of types of data are stored in memories corresponding to a nozzle group and the plurality of fluids are ejected from the nozzle group. SOLUTION: In the fluid consumption measuring device, image data for three colors (Y, M, C) are stored in a RAM 52c corresponding to a nozzle row NZ3, and ink droplets of the corresponding colors are ejected from sub-nozzle groups NZy, NZm, NZc via a head driving circuit 33. The image data for the two colors out of the three colors are stored in the other RAMs 52d, 52e, individually, and dot counters 53a to 53e count the numbers of dots, based on the image data from the corresponding RAMs 52a to 52e. A computation section 51 computes ink consumptions for the respective colors, based on counted values acquired from the dot counters 53d, 53e, and subtracts the total value of the counted values acquired from the dot counters 53d, 53e, from a counted value for the three colors acquired from the dot counter 53c, followed by computing an ink consumption for the remaining color.
