1. A recording apparatus comprising:
a recording head including a plurality of heating elements arranged in a predetermined direction, configured to heat, based on image data, a sheet-like recording medium formed of a plurality of laminated color-developing layers for developing a plurality of colors when heated, and develop a color of a specific color-developing layer among the plurality of color-developing layers to form an image on the recording medium;
a first condition determination unit configured to determine whether a first condition is satisfied, the first condition indicating that a subsequent pixel, located at a same position as a target pixel in the predetermined direction and to be recorded following the target pixel, is a pixel for developing a color of a bottom color-developing layer of the recording medium; and
a pulse control unit configured to control a pulse to be applied to the recording head in forming the target pixel, based on the determination result of the first condition determination unit,
wherein, in a case where a value of the target pixel in the image data is a predetermined value and does not satisfy the first condition, the pulse control unit controls the pulse so that a thermal energy to be applied to the recording medium by the recording head in forming the target pixel is lower than a thermal energy to be applied in a case where the value of the target pixel in the image data is the predetermined value and the first condition is satisfied.
