Abstract
Abstract An image receiving sheet is provided which can offer good toner fixation and stably provide excellent image quality, has no significant dependency upon environmental conditions, has constant surface electric resistivity, and can be used also in electrophotography wherein no silicone oil is used at the time of fixation of the toner. Provision of a receptive layer 2 provided on at least one side of a substrate 1, the receptive layer 2 comprising a thermoplastic resin and a conductive material not utilizing ionic conduction, can provide an image receiving sheet 4 that has antistatic properties and surface electric resistivity which are stable against a fluctuation in environmental conditions around the image receiving sheet.
