ABSTRACT:
A substantial change in charge on toner in a development station due to a reduction in relative humidity as the station warms up is compensated for by applying heat from an externaI source to the station when the station has not been warmed up. For example, when the station is turned off or in a condition of idle. This feature is particularly usable in a station having a rotating magnetic core.
