Provided are a liquid ejection apparatus and a maintenance apparatus capable of suppressing unintended movement of a wiping unit. The maintenance apparatus includes: a wiping unit configured to wipe the ejection opening surface of a liquid ejection head in which ejection openings over a length corresponding to the width of a print medium are formed; and a lock member configured to restrict movement of the wiping unit from a position to which the wiping unit is evacuated from the ejection opening surface.

Liquid ejection apparatus and maintenance apparatus

A replenishing apparatus includes a rotatable cylindrical-shaped container having a discharge opening through which toner is discharged, and a guide member provided rotatably with the container. The guide member has a first face on an inner face of the container and a second face which guides the toner scooped by the first face toward the discharge opening. A controller controls a drive portion to rotate the container in a first mode that performs replenishment control in a first drive condition and in a second mode that performs replenishment control in a second drive condition in which a quantity of rotation of the container per unit time is less than the first drive condition. The controller switches the mode from the first mode to the second mode based on a detection result about a quantity of developer.
