ABSTRACT:
A development system for developing latent magnetic images with magnetic toner comprises a developer housing having an upper chamber communicating through a selectively variable opening with a lower chamber, the lower chamber defining the development zone and being provided with peripheral edge seals. In operation, magnetic toner is gravity fed through the selectively variable opening to the lower chamber, filling the lower chamber to provide flood contact development of the latent magnetic image residing on a magnetizable member which is moved in a direction counter to that of gravity flow. Optional baffles are preferably included in the developer housing and above the development zone to prevent machine contamination by toner powder cloud during high speed development.
