ABSTRACT:
The present invention relates to diazo copiers and is concerned with the supply of gaseous developing agent to a developing section of a copier, and the removal of surplus developing agent from this section of the copier, and from the developed copy material. The copier apparatus includes means to pass the developing agent (a gas) from a reservoir and through a gas governor. The governor functions to reduce the gas pressure to a set, lower value. The lower pressure gas then enters a development chamber through which the material for development also passes. Surplus gas is removed from the material for development by a heating and suction means.
