1. A curing device comprising:
a light emitting member having a plurality of light sources, each of the plurality of light sources being configured to emit light to cure liquid on a printing medium, the plurality of light sources including a first light source and a second light source, each of the plurality of light sources and the printing medium being configured to be located with a gap therebetween;
a moving device configured to relatively move the printing medium and the light emitting member in a moving direction orthogonal to a direction in which the printing medium and the light emitting member are aligned; and
a control device configured to perform:
based on information indicating that a first gap between the first light source and the printing medium is smaller than a threshold value and a second gap between the second light source and the printing medium is greater than or equal to the threshold value,
controlling the first light source to emit light of a first intensity while controlling the moving device to relatively move the printing medium and the light emitting member in the moving direction; and
controlling the second light source to emit light of a second intensity which is greater than the first intensity while controlling the moving device to relatively move the printing medium and the light emitting member in the moving direction.
