Claim:
An image recording apparatus, comprising: a housing; a recording head which ejects droplets of at least one sort of ink and thereby records an image on a recording medium; a carriage which is provided in the housing and which carries the recording head and reciprocates in opposite directions intersecting a feeding direction in which the recording medium is fed, wherein the carriage includes a tube connection portion; at least one ink supply tube which is connected, at one end thereof, to the tube connection portion of the carriage so as to supply said at least one sort of ink to the recording head, and is fixed, at a fixed portion thereof, to the housing such that an intermediate portion thereof located between said one end thereof and said fixed portion thereof forms a first curved portion that is convex in one of said opposite directions, wherein said at least one ink supply tube has a first flexibility assuring that when the carriage reciprocates, said at least one ink supply tube follows reciprocation of the carriage while said first curved portion thereof changes a shape thereof; a pivotable support member which is supported by the housing such that the pivotable support member is pivotable about a supporting point, wherein the pivotable support member includes an arm portion which extends from the supporting point and has a first support portion that supports a portion of the first curved portion of said at least one ink supply tube; and a biasing device which biases the pivotable support member in a biasing direction to cause the pivotable support member to pivot in a direction to decrease a radius of curvature of the first curved portion of said at least one ink supply tube.
