Abstract (en)

[origin: DE19819390A1] The image development involves a toner reservoir (4) which supplies toner particles (5), and a development roller (2) which receives and transports the charged particles to a gap between the development roller and an image carrier (1). A further roller (6) along the path from the toner source to the development roller facilitates an even toner distribution of a defined thickness. The surfaces of the development and further rollers are separated by a gap wider than the average diameter of the toner particles.
