Abstract

The invention relates to an improvement in diazocopy development machines. A development chamber is used in which ammonia vapors are generated. A converging system made up of converging walls which accelerate the hot ammonia vapors, without additional means, channels the vapors toward the copy support. Thus, a striking is made of the support with the vapors and the development speed can be significantly increased.
