To provide a color diffusion transfer photographic film unit excellent in uniformity of an image even at low temperature and capable of obtaining an excellent image having high maximum image density and low minimum image density.

The color diffusion transfer photographic film unit capable of forming a color image on an image receiving element is developed in the presence of a compound of the formula [Rf-(Rc)n]mZ (where Rf is perfluoroalkyl; Re is alkylene; Z is a group having an anionic group, a cationic group, a betaine type group or a nonionic polar group required to impart surface activity; n is 1; and m is an integer of 1-3).
