Abstract: The present invention provides a toner for developing an electrostatic latent image comprising at least a core layer including at least a coloring agent and a first binder resin, and a shell layer for covering the core layer and including a second binder resin, wherein two local maximum values of the tangent loss (tan ?) of the dynamic visco-elasticity are present in a temperature range of 90° C. or less, with one of the local maximum values present in a range of less than 60° C., and the other local maximum value present in a range of 60° C. or more and 90° C. or less. Moreover, a production method for the toner for developing an electrostatic latent image, a developer for developing an electrostatic latent image, using the toner, and an image forming method are provided.

Abstract: A photoreceptor for electrophotography is disclosed. Thickness of the under coat layer is 6-15 ?m, thickness of the charge transport layer is 5-15 ?m, and coefficient of working function of the under coat layer ? is not more than 0.8.

Abstract: The present invention relates to a process for preparing a toner for electrophotography containing a resin binder and a colorant, including the step of preparing fine particles of the resin binder to have a volume-median particle size (D50) of from 0.05 to 3 ?m in an aqueous medium in the presence of a nonionic surfactant within a temperature range of from 10° C. below to 10° C. above a cloud point of the nonionic surfactant; and a toner for electrophotography obtained by the process as defined above, wherein the toner contains 60% by weight or more of a crystalline polyester and has a volume-median particle size (D50) of from 1 to 7 ?m. The toner obtained according to the process of the present invention can be suitably used, for example, in development of a latent image formed in electrophotography, electrostatic recording method, electrostatic printing method, or the like.

Abstract: By using a high or low viscosity transparent toner, with respect to the other color toners, and different amounts of transparent toner lay-down, the gloss of an image printed by an electrophotographic device may be adjusted. By also applying the transparent toner as a negative mask, the differential gloss of the image may be reduced while still adjusting the gloss of certain portions of the image. Further, because different gloss levels may appear different at different viewing angles, transparent toner may be laid down to encode a transparent image within the image being printed. Such a transparent image may be useful as, for example, an authentication means for a document. Additionally, by varying the gloss levels on particular aspects of a printed image, multiple images of different gloss levels, which are prominent at different viewing angles can be made, thereby, a three-dimensional image effect can be achieved on the printed page.

Abstract: A toner composition includes core particles including a polymeric latex and an optional colorant, and amino-containing polymer particles dispersed on an external surface of the particles.
