Abstract
An apparatus for the production of a toner from a starting material having a fluidity includes a head portion and a solidifying portion. The head portion for ejecting the starting material includes a starting material storing portion, which stores the starting material, a piezoelectric material, which generates a pressure pulse for applying the pressure pulse to the starting material and an ejection portion, which ejects the starting material with the pressure pulse. The solidifying portion solidifies the starting material ejected from the head portion into a particulate material.
Claims73
An apparatus for producing a toner from a starting material having a fluidity, comprising:
- a head portion, including:
- a starting material storing portion which stores the starting material;
- a piezoelectric material, which generates a pressure pulse and applies the pressure pulse to the starting material;
- and
- an ejection portion, which ejects the starting material with the pressure pulse from the head portion;
- and
- a solidifying portion, which solidifies the starting material ejected from the head portion into a particulate material.
An apparatus for producing a toner from a starting material having a fluidity, comprising:
- a head portion, including:
- a starting material storing portion, which stores the starting material;
- a heating element, which applies a heat energy to the starting material to generate an air bubble in the starting material storing portion;
- and
- an ejection portion, which ejects the starting material with the volume change of the air bubble;
- and
- a solidifying portion, which solidifies the starting material ejected from the head portion into a particulate material.
A method for producing a toner from a starting material having a fluidity, comprising the steps of:
- ejecting the starting material intermittently with a pressure pulse generated by a piezoelectric material from a head portion;
- and
- solidifying the starting material while being conveyed with an air flow through a solidifying portion to form a particulate material.
24 The method as set forth in claim 21, further comprising the steps of:
- providing a gas flow in substantially one direction;
- and
- discharging the starting material ejected by the pressure pulse into the gas flow.
