    摘要： An electrophotographic method for producing fused toner images on a receiver medium comprising the steps of: forming an electrostatic image pattern on an image forming member; developing the image pattern on the image forming member with fusible toner particles thereby forming a toner image thereon; transferring the toner image to the receiver medium; and heating the toner image to form a fused toner image on the receiver medium, wherein an amount of a plasticizer is added to the toner particles of the toner image after formation of the toner image on the image forming member and prior to or concurrent with fusing of the transferred toner image on the receiver medium, further wherein the amount of plasticizer added is effective in lowering the Tg of the toner below that of the toner under prevailing ambient conditions in the absence of the added plasticizer. The current invention overcomes the limitations of the prior art because the plasticizer is added immediately before fusing, thus avoiding toner clumping upon storage, as well as eliminating the high cost associated with a custom manufactured receiver that already contains plasticizer.

    摘要： A process of producing an image including transferring porous polymeric marking particles to a receiver, and fixing the marking particles to the receiver by applying heat and pressure by contacting the marking particles with a heated fuser member including a topcoat layer having a storage modulus of at least 10 MPa at 175° C. In particular embodiments, the invention is specifically directed towards fusing porous toner materials, and enables reducing the image relief, toner spread, and differential gloss of resulting fused toner images. Higher gloss and reduced differential gloss is obtained at similar or reduced toner spread, measured by toner particle area gain, allowing the use of reduced fusing conditions compared to solid toners.
