Abstract
In a printer in which a plurality of holes to be filled with ink is formed in an ink film, selectively heating ink generates bubbles from the holes and ejects ink due to the pressure of bubbles, thus printing an image on a sheet. The ink film having the holes satisfies relations H.gtoreq.2P and V.gtoreq.2P +D when the diameter of the holes is given as D, the pitch between two adjacent holes is given as P, the width of a heating element in a direction perpendicular to the moving direction of the sheet is given as H, and the width of the heating element in the moving direction of the sheet is given as V.
