Liquid droplet ejection head and image forming apparatus

摘要

The liquid droplet ejection head comprises: a base plate which has a common supply flow channel formed throughout an entire dimension in a lengthwise direction of the base plate; a plurality of short head modules which are assembled on the base plate to form a long head, each of the plurality of short head modules including ejection ports ejecting droplets of liquid and a liquid flow channel supplying the liquid to the ejection ports from the common supply flow channel; and a positioning mechanism through which the short head modules are detachably installed on the base plate.
