To provide a developing apparatus that can achieve rapid development without changing a conventional apparatus structure as much as possible.

The developing apparatus includes a color developing tank which reserves a color developing liquid to develop colors of an exposed photosensitive material P, a bleach-fixing tank 52 which reserves a bleach-fixing liquid to bleach-fix the photosensitive material P, and a stabilizing tank 53 which reserves a stabilizing liquid to stabilize the photosensitive material P, wherein a UV ray irradiating means 9 is disposed along the passage at least before the photosensitive material P is sent to the stabilizing tank 53, and the UV irradiating means 9 irradiates the emulsion surface P1 of the photosensitive material with UV rays.
