Zusammenfassung: | PROBLEM TO BE SOLVED: To provide an image formation apparatus capable of preventing ink mist, which is extremely fine ink droplets floating in a used machine, from adhering to a linear encoder scale. SOLUTION: The image formation apparatus has a print head for forming images on a recording medium, a carriage 11 on which the print head is mounted and which carries out scanning in the direction orthogonal to the conveyance direction of the recording medium, an encoder member 7 having an encoder scale on which a predetermined pattern is printed, and an encoder sensor 8 which is provided at the carriage 11 to detect the encoder scale. The encoder member 7, whose cross sectional shape in the carriage moving direction is formed to be a tubular shape which has at least one flat side and is partially open, has the encoder scale 28 on any surface formed by the flat side in the carriage moving direction.
