A process for producing a toner for developing electrostatic image is disclosed which comprises preparing a suspension of a mixed solution of a polymerizable monomer system containing at least a coloring agent and a release agent and an aqueous medium system and polymerizing the suspension, wherein the suspension is prepared by jetting the mixed solution through a nozzle under elevated pressure in a flowing direction which is forced to vary so that the mixed solution collides with each other or with a predetermined plane to prepare suspended grains, and immediately passing the mixed solution through an apparatus for throttling the path so that back pressure and shearing stress produced by the throttling apparatus are used to adjust the grain diameter and grain size distribution of the suspended grains. The process provides a toner having a small grain diameter and a narrow grain size distribution and comprising additives homogeneously dispersed therein.

摘要:
A method for processing a separation and rupture portion of a display label is a method for forming, on the display label attached to an attachment target object, the separation and rupture portion for rupturing the display label upon separation of the display label from the attachment target object. This method includes attaching, to the attachment target object, the display label having a back side on which an adhesive layer is formed, and then forming a slit serving as the separation and rupture portion on the display label.
