It remains constant because the gray body's absorptivity is independent of wavelength and temperature.

A grey body is also defined as one whose absorptivity of a surface does not vary with the temperature and wavelength of the incident radiation.

All the Radiation property (like absorptivity, emmisivity) is same for all the wavelength falling on Grey Body.
