Abstract
The invention contemplates electrostatic recording apparatus in which a toner image consisting of toner particles of at least two different kinds and of different polarities is efficiently and reliably transferred to a recording medium, such as an ordinary sheet of paper. The toner particles having different polarities are all converted into those having one polarity, and after such conversion the toner image (with its two kinds of particles) is electrostatically transferred to the recording medium, the transfer involving both kinds of particles at the same time. Various embodiments are described.
