Use of electrophotographic techniques to digitally produce images on textiles and non-planar substrates can be accomplished if the adhesion forces between the toner and the photoconductor are sufficiently reduced and/or that the forces between the toner to the receiver are greater than those adhering the toner to the photoconductor.
