Abstract
The present invention relates to a high intensity blending method for producing surface modifications to electrophotographic and related toner particles. The improved method utilizes an improved blending tool comprising a shank having riser members at each end, such risers being angled to the axis of the shank between 10 and 16 degrees and having a height dimension greater than 20 percent of the diagonal dimension of the shank.
Claims20
A method of blending toners, comprising
- (a) adding toner particles comprising a mixture of toner resin and colorants to a blending machine;
- (b) adding surface additive particles to the mixture of toner particles;
- and
- (c) blending the toner particles and surface additive particles in the blending machine using a rotating blending tool comprising a center shank having a long axis, at least one end, and an end region proximate to the end plus a riser member fixedly mounted during rotation at the end region of the shank, said riser member having an outside surface with a forward region, wherein the forward region is outwardly angled from the long axis of the shank at an angle between 10 and 16 degrees.
17) An improved method of blending toners comprising:
- (a) adding toner particles comprising a mixture of toner resin and colorants to a blending machine;
- (b) adding surface additive particles to the mixture of toner particles;
- and
- (c) blending the toner particles and surface additive particles in the blending machine using a rotating blending tool comprising a shank having a diagonal dimension, at least one end, and an end region proximate to the end and a riser member fixedly mounted during rotation at the end region of the shank, said riser member having a height dimension wherein the ratio of the height dimension to the diagonal dimension of the shank is greater than 0.20.
