Liquid discharge head and liquid discharge apparatus provided with the same

A liquid discharge head, comprising:

• a plurality of individual channels;
• a supply channel connected to inlets of the individual channels and through which liquid is supplied to the individual channels;
• a recovery channel connected to outlets of the individual channels and through which the liquid is recovered from the individual channels,
• wherein each of the individual channels includes:
• a nozzle;
• an upstream-side pressure chamber disposed between the nozzle and the supply channel;
• a downstream-side pressure chamber disposed between the nozzle and the recovery channel;
• an upstream-side throttle channel connecting the supply channel and the upstream-side pressure chamber;
• and
• a downstream-side throttle channel connecting the recovery channel and the downstream-side pressure chamber,
• the liquid discharge head further comprising:
• an upstream-side actuator configured to apply pressure to the liquid in the upstream-side pressure chamber;
• and
• a downstream-side actuator configured to apply pressure to the liquid in the downstream-side pressure chamber,
• wherein a channel resistance of the upstream-side throttle channel is smaller than a channel resistance of the downstream-side throttle channel.
