| 摘要 |
A printer unit of a printer device having at least one printer unit which includes at least one toner container for toner particles and an electrode unit, including electrodes and apertures surrounded at least partly by the electrodes. The electrode unit is arranged to control the transportation of the toner particles by means of attraction fields from a toner carrier member arranged in the toner container or in a space communicating with it towards a back electrode and an information carrier insertable between the toner carrier member and the back electrode. The toner carrier member, the electrode unit, and/or the back electrode are arranged to form a transportation zone between two most remote transversal electrodes and generate the attraction fields, which through the apertures attract the toner particles towards the back electrode. The transportation zone consists of at least two smaller zones including, in the toner container or in a space communicating with it, a number of toner carrier members corresponding to the number of the zones and groups of electrode units consisting of apertures and electrodes having reduced numbers and/or sizes.
