A process of electrostatically printing a design on fabrics which comprises forming an electrostatic latent image corresponding to the design on a photoconductive material or an insulating dielectric material, developing the latent image with a toner comprising at least one chargeable resin and at least one colorant, transferring the developed toner image directly to a fabric having a surface inherent resistivity, as measured at a temperature of 20.degree. C and a relative humidity of 65%, of about 1 .times. 10.sup.6 to about 1 .times. 10.sup.14 ohms, and fixing the toner image to the fabric. When the transferring of the toner image is carried out using a corona discharge, a smooth sheet having a volume inherent resistivity of about 1 .times. 10.sup.6 to about 1 .times. 10.sup.20 ohms and a dielectric constant of about 2 to about 40 can be overlaid on the fabric to apply corona discharge through the sheet and thereby produce better results.
