Abstract
A system is described for transporting sheet-like material. The sheet has a powder, such as electrographic toner particles, loosely attached to it at one or both sides. The particles may be laid down in an image-wise manner by an electrophotographic or direct electrographic system, such as a printer or a copier. The sheet is transported by an endless belt or by a drum. In order to preserve the location of toner particles on the sheet, and to establish correct transportation of the sheet, electrostatic charges are applied either to the sheet or the transporting member or both. As such, the sheet suitably adheres to the transport system and electrostatically loaded toner particles may even adhere better to the sheet.
