Abstract: A toner includes a crystalline polyester resin in an amount equal to or greater than 25% by mass. The toner satisfies the following formula when the toner is tested using a capillary rheometry measurement during which a pellet of the toner is pressed by a member while being heated: 0.3≤(first temperature−second temperature)/(second temperature−third temperature)≤1, where the first temperature is a temperature at which the member falls 4 mm, the second temperature is a temperature at which the member falls 2 mm, and the third temperature is a temperature at which the member starts to fall.

Abstract: An electrostatic charge image developing white toner according to the present invention includes toner base particles including rutile type titanium oxide particles as colorant and a binder resin. The rutile type titanium oxide particles are composed of two groups Ga and Gb of rutile type titanium oxide particles have different volume particle size distribution. A volume particle size distribution curve of the rutile type titanium oxide particles represents diameter on a horizontal axis and volume ratio on a vertical axis and has two main peaks. Diameters Da and Db of peak top positions of the two main peaks are respectively within a range of 100 to 500 nm, and satisfy following Relational expressions: 25 nm≦Db−Da≦200 nm (Relational expression 1): (mass of Ga):(mass of Gb)=5:95 to 30:70 (Relational expression 2):

Abstract: A chemically prepared core shell toner formulation for use in electrophotography having an inventive softening agent consisting of a core shell latex having an encapsulated interpenetrating polymer network microgel in the core of the toner is disclosed. Having this core shell latex with an encapsulated IPN microgel in the core of the toner results in a toner that can simultaneously fuse at a desirable low temperature and survive the temperature extremes associated with shipping and storage.

Abstract: A method includes grinding a wax into wax particles having a size in a range from about 600 microns to about 800 microns forming a mixture of the wax particles with water and a surfactant; and homogenizing the mixture to form a wax dispersion, the homogenizing step is maintained below about 35° C. A wax dispersion includes a wax a surfactant; and water, particles of the wax dispersion are a uniform, irregular, non-platelet morphology. A wax dispersion made by a process includes grinding a wax into wax particles having a size in a range from about 600 microns to about 800 microns, forming a mixture of the wax particles with water and a surfactant, and homogenizing the mixture to form a wax dispersion, the homogenizing step is maintained below about 35° C. and the wax has a uniform, irregular, non-platelet morphology imparted by combination of the grinding and homogenizing steps.
