Abstract
There is provided a method and apparatus for forming an image which includes providing a recording composition capable of changing its adhesivity corresponding to the polarity of a voltage applied thereto between a pair of electrodes. The recording composition has a transfer characteristic having a tendency to change by loss of at least one component of the recording composition. A voltage is applied between the pair of electrodes to attach the recording composition to one of the pair of electrodes to attach the recording composition to one of the pair of electrodes. Any such change in the transfer characteristic of the recording composition is detected during the process. In response to any change in the transfer characteristic additional component is added to the recording composition to compensate for that change.
