A liquid jet recording head comprises a discharging orifice for forming flying droplets by discharging a liquid; a liquid pathway having a bent portion, an energy acting portion forming at least a part of said liquid pathway where the liquid filling the internal portion thereof is subjected to energy for droplet formation and an energy generating element for generation of droplet forming energy to be transmitted to the liquid filling said acting portion. The principal part of the wall surface of said liquid pathway is formed of a hardened photosensitive resin.
1. A liquid jet recording head, comprising a substrate, a hardened photosensitive material on such substrate defining a plurality of liquid pathways, as hardened photosensitive material constituting the side walls of said liquid pathways, a plurality of energy generating elements disposed on said su
1. A liquid jet recording head, comprising a substrate, a hardened photosensitive material on such substrate defining a plurality of liquid pathways, as hardened photosensitive material constituting the side walls of said liquid pathways, a plurality of energy generating elements disposed on said substrate with one said energy generating element for each of said liquid pathways, and a plate having formed therein a plurality of discharging orifices, with one said discharging orifice for each of said liquid pathways for discharging liquid from the corresponding said liquid pathway, wherein said energy generating elements are disposed to expel liquid through said orifices in a direction substantially perpendicular to the surface of said substrate, and wherein said substrate, said hardened photosensitive film and said plate are laminated together in that order. 2. A liquid jet recording head according to claim 1, wherein each said discharging orifice is provided at the corresponding said energy generating element. 3. A liquid jet recording head according to claim 1, wherein said plate is composed of a hardened photosensitive film. 4. A liquid jet recording head according to claim 1, wherein each energy generating element is a heating element. 5. A liquid jet recording head according to claim 1, wherein said energy generating elements communicate with a common liquid supplying pathway. 6. A liquid jet recording head according to claim 1, wherein each said energy generating element is provided in the corresponding said liquid pathway. 7. A liquid jet recording head according to claim 6, wherein the liquid is supplied from two directions to each said energy generating element. 8. A liquid jet recording head according to claim 6, wherein the liquid flows by passing through said energy generating elements. 9. A liquid jet recording head which comprises a body having a plurality of discharging orifices for formation of flying droplets by discharging a liquid; a liquid chamber having a floor and having at least one liquid supply inlet for supplying the liquid, said liquid chamber being in communication with each of said discharging orifices; and a plurality of heating elements for generation of heat energy provided on the floor of said liquid chamber with one heating element for each said discharging orifice, said plurality of heating elements being provided so that each faces towards its corresponding discharging orifice for expelling liquid through said orifice in a direction substantially perpendicular to the surface of said floor of said liquid chamber, wherein the flying droplets are formed by heat energy generated from said heating elements acting on the liquid to generate liquid discharging force. 10. A liquid jet recording head according to claim 9, wherein said liquid chamber is sub-divided two-dimensionally into compartments of a number corresponding to the number of said plurality of heating elements. 11. A liquid jet recording head according to claim 9, further comprising a plurality of liquid chambers. 12. A liquid jet recording head which comprises a body having a plurality of discharging orifices for formation of flying droplets by discharging a liquid; a liquid chamber having a floor and having at least one liquid supply inlet for supplying the liquid, said liquid chamber being in communication with each of said plurality of discharging orifices; and a plurality of energy generating elements for generation of droplet forming energy provided on the floor of said liquid chamber with one heating element for each said discharging orifice, said plurality of energy generating elements being provided so that each faces toward its corresponding discharging orifice for expelling liquid from said orifice in a direction substantially perpendicular to the surface of said floor of said liquid chamber, wherein at least a part of the wall surface of said liquid chamber is formed of a hardened photosensitive resin. 13. A liquid jet recording head according to claim 12, wherein said liquid chamber is sub-divided two-dimensionally into compartments of a number corresponding to the number of said plurality of energy generating elements. 14. A liquid jet recording head according to claim 12, further comprising a plurality of liquid chambers.
