Reverse development method |
摘要 |
A reverse development is performed with application of development bias voltage to a development sleeve at the time of development, and the polarity of the bias voltage is reversed or the bias voltage is reduced to zero at the time of non-development. Furthermore, positive images and negative images can be selectively formed by changing the voltage to be applied to a charge injection electrode, without changing the bias voltage to be applied to the development sleeve.
