1. An image forming system comprising:
a sensor unit including a light source that irradiates a medium being conveyed with light, and a gloss sensor that receives light emitted from the light source and specularly reflected on the medium, and detects a diffusion distribution of light in the medium;
a detection condition setting unit that identifies a type of the medium being conveyed and sets a light amount of the light source and/or exposure time of the gloss sensor at time of glossiness detection in accordance with the type of the medium; and
a glossiness detector that detects glossiness of the medium from the diffusion distribution of light detected by the gloss sensor under a detection condition set by the detection condition setting unit.
