Abstract
In a color inkjet printing apparatus using an ink circulation system, there is provided an inkjet printing apparatus capable of making appropriate circulation control for individual inks without resulting in cost increase. To achieve this, an inkjet printing apparatus includes a plurality of diaphragm pumps for circulating ink within a print head, a sub-tank, a supply flow path, and a collection flow path. The plurality of diaphragm pumps are configured by mounting control members of different types which can press against diaphragm units of a same type.
