Abstract

TONER DE ALTO BRILHO COM AGREGAçãO EM EMULSãO E ADIçãO DE CáLCIO A presente invenção refere-se a um toner que inclui partículas de toner que têm um material que contém cálcio pelo menos em uma parte da superfície das partículas do toner, onde as partículas do toner contém cálcio em uma quantidade entre cerca de 20 ppm e cerca de 300 ppm de cálcio em peso seco do toner; um revelador que inclui um carreador e um toner, onde o toner inclui partículas de toner que têm um material que contém cálcio pelo menos em uma parte da superfície das partículas do toner; um processo de agregação em emulsão para fabricar partículas de toner, no qual as partículas de toner são tratadas com cálcio. A adição de cálcio às partículas do toner melhora o desempenho do toner, baixando a coesão e o carregamento elétrico, gerando desta forma uma imagem de alto brilho.
