摘要：PROBLEM TO BE SOLVED: To provide an ejection weight measurement method which practices an ejecta weight measurement for accurately measuring an ejection weight and due to the practice of the ejection weight measurement, suppresses an increase in a time necessary for drawing an image by liquid droplet ejection by suppressing a time during which an image drawing ejection step of ejecting a liquid onto an object on which an image is drawn is not in operation, to provide a liquid droplet ejection head maintenance method, to provide a liquid droplet ejection apparatus, and to provide a liquid droplet ejection apparatus. SOLUTION: The ejection weight measurement method is a method for measuring ejection weights in liquid droplet ejection heads in a liquid droplet ejection apparatus having a head group comprising a plurality of first liquid drop ejection heads in which liquid feed requirements for feeding a liquid are common to the respective liquid ejection heads that eject the liquid and includes the weight measurement step of estimating the ejection weights in the respective liquid drop ejection heads of the plurality of the first liquid ejection heads constituting the head group by measuring the ejection weights in the plurality of the first liquid ejection heads constituting the head group.
