To provide a heat developing device that securely removes dust sticking on the top surface of a photosensitive heat-developed recording material by sticky rollers and prevents sticky rollers from sticking on each other and is free of an increase in rotational load due to sticking between sticky rollers.
The heat developing device 100 which heats the photosensitive heat-developed recording material A to develop a latent image recorded on an image formation layer 35 is characterized in that a 1st sticky roller 85 which is arranged upstream from a development section 47 for the photosensitive heat-developed recording material A in a conveying direction and comes into contact with one surface 33a of the conveyed photosensitive heat-developed recording material A and a 2nd sticky roller 87 which comes into contact with the other surface 33b of the photosensitive heat-developed recording material A are arranged across a conveyance path for the photosensitive heat-developed recording material A. Then foreign matter sticking on surfaces of the photosensitive heat-developed recording material A is sticky removed.
