IMAGE FORMATION DEVICE, DISCHARGE DETECTION UNIT, AND LIQUID DISCHARGE DEVICE

摘要

PROBLEM TO BE SOLVED: To solve a problem that a waste liquid transferred to a wipe member is dropped from an end part or deposits and grows to contact with a nozzle surface when the liquid adhering to an impact member is wiped with the wipe member.SOLUTION: A discharge detection unit 100 includes a box shaped holder member 103. An island-like electrode holding part 104 is formed in the holder member 103. An electrode plate 101 is disposed on an upper surface of the electrode holding part 104 which faces a nozzle surface 41 of a recording head 4. A waste liquid receiving part 110 is formed by a groove formed in an area of the holder member 103 which is located between a periphery of the island-like electrode holding part 104 and an outer wall part 103a.
