摘要： A recording apparatus includes a print head, a recovery unit, a type obtaining unit, a threshold obtaining unit, and a calculation unit. The print head forms an image by applying a recording material to a recording medium. The recovery unit performs a recovery operation for recovering an ejection state of the print head. The type obtaining unit obtains a type of the recording medium on which the image is to be recorded. The threshold obtaining unit obtains a threshold for performing the recovery operation corresponding to the obtained type of the recording medium. The calculation unit calculates a count-up value by adding, in response to recording on the recording medium, an addition value set for each of types of recording media. The recovery operation is performed in a case where the count-up value calculated by the calculation unit exceeds the threshold obtained by the threshold obtaining unit.

摘要： A recording apparatus includes a conveying unit, a supporting unit, and a static elimination unit. The conveying unit conveys a recording medium in a first direction to a recording area where recording is performed by a recording unit. The supporting unit supports the recording medium conveyed by the conveying unit and includes an abutment surface that abuts the recording medium when the supporting unit supports the recording medium. The static elimination unit eliminates static from the recording medium in a static elimination portion. The static elimination portion is not provided at a position opposed to the abutment surface and is provided at a position not opposed to the abutment surface in the supporting unit.
