A liquid ejection recording apparatus has a substrate section and a support member. The substrate section has orifices for discharging ink droplets, resistors for generating thermal energy upon application of a voltage, and connector pins. The support member has an ink supply pipe and connector sockets for receiving the connector pins of the substrate section when the substrate section is mounted and supported on the support member. Ink can be supplied from an ink tank or a replaceable ink pack in the support member or can be supplied from a separate location through a pipe. Electrical signals for recording can also be supplied to the substrate section from a remote location through a flexible cable. The substrate section can be easily removed from the support member for replacement.
