Total Claims: 7
Claim 1
Independent Claim
40 words
A toner for developing an electrostatically charged image, composed of associated particles of secondary particles comprising primary particles of a polymer having an acidic or basic polar group and particles of a coloring agent and optionally a charge controlling agent.
Claim 2
Dependent Claim
40 words
A toner for developing an electrostatically charged image, composed of associated particles of secondary particles comprising primary particles of a polymer having an acidic or basic polar group and particles of a coloring agent and optionally a charge controlling agent.
Claim 3
Dependent Claim
24 words
The toner set forth in claim 1 in which the contacting portions among the secondary particles are at least partly melt-adhered by film formation.
Claim 4
Dependent Claim
122 words
A process for producing a toner for developing an electrostatically charged image composed of associated particles of secondary particles comprising primary particles of a polymer having an acidic or basic polar group and particles of a coloring agent and optionally a charge controlling agent, which comprises adding the coloring agent and optionally a charge controlling agent to an emulsion of the polymer, heating the mixture at 20 to 45 °C for 1 to 3 hours with stirring, then heating the mixture with stirring at a temperature from the glass transition temperature of the polymer to a temperature 65 °C higher than the glass transition temperature for 1 to 3 hours, filtering the resulting associated particles optionally, and then drying the associated particles.
Claim 5
Dependent Claim
122 words
