The spectral-characteristic acquisition apparatus includes a conveyor including a first conveyance roller pair disposed in a conveyance direction in which an object is conveyed and a second conveyance roller pair disposed downstream from the first conveyance roller pair in the conveyance direction, a sensor to detect that the object has reached the second conveyance roller pair, circuitry to control the second conveyance roller pair to drive by a predetermined amount with a driving force greater than a driving force of the first conveyance roller pair upon detecting that the object has reached the second conveyance roller pair by the sensor and to stop driving, and a color data obtainer to obtain color data from the object at a position where the object stops moving. In the spectral-characteristic acquisition apparatus, the circuitry estimates a spectral characteristic of the object.
