PROBLEM TO BE SOLVED: To provide a high density and highly reliable liquid discharge head capable of stably discharging despite the environmental change, a head cartridge, and an image forming apparatus. SOLUTION: The liquid discharge head has a liquid chamber unit constituted by connecting a nozzle substrate having nozzles for discharging liquid, a liquid chamber for storing the liquid in communication with the respective nozzles including flowing channels, and a diaphragm formed at least a part of the wall of the liquid chamber, a drive means for generating pressure for pressurizing the liquid in the liquid chamber, a frame member supporting the liquid chamber unit and having a common liquid chamber, and a heating means for heating the liquid discharged by the frame member. Further, the frame member in the liquid discharge head is formed of a plurality of kinds of members having different thermal conductivities, a site having the heating means of the frame member is formed of a high thermal conductive member, and a site formed of a low thermal conductive member is arranged in the drive means side of the high thermal conductive member.
