摘要： An liquid circulation device comprises a liquid casing, a gas replenishing section and a liquid replenishing section. The liquid casing retains liquid to be supplied to a liquid ejection section for ejecting the liquid and includes a liquid chamber connected with the liquid ejection section in such a manner that the liquid can be circulated therebetween. The ink circulation device increases pressure inside of the liquid casing by replenishing the gas to the liquid casing with the gas replenishing section and replenishing the liquid to the liquid casing with the liquid replenishing section, and meets a relation
(ΔP1*(d1)^2/L1)/(ΔP2*(d2)^2/L2)>µ1/µ2, that is, (ΔP1·(d1) 2 /L1)/(ΔP2·(d2) 2 /L2)>µ1/µ2.
