A conveying apparatus that rotates a roller and conveys an object, the conveying apparatus including: a roller driving unit that rotates the roller; a first operation unit that operates a rotation amount of the roller corresponding to a target movement amount of the object, on the basis of the target movement amount and information of a roller diameter, and quantizes the rotation amount; a random number generating unit that generates a random number; a second operation unit that operates a corrected rotation amount of the roller obtained by correcting the rotation amount, on the basis of the random number generated by the random number generating unit, a quantization error obtained by the first operation unit and a quantization method; and a driving control unit that controls driving of the roller according to the corrected rotation amount.
