Abstract
A liquid ejection apparatus includes: a liquid ejection head configured to eject liquid; a liquid storage container including a storage portion configured to store liquid to be supplied to the liquid ejection head, an opening configured to supply liquid from a liquid refill container to the storage portion, and a cover member configured to be in a first state to cover the opening and a second state to expose the opening; and a regulation unit configured to regulate transition from the first state to the second state of the cover member. Regulating by the regulation unit is released when a first portion, of the liquid refill container, configured to prevent misfilling the storage portion with an incorrect liquid, is fitted into a second portion of the liquid ejection apparatus.
