POSITIVELY-CHARGED TONER FOR ELECTROSTATIC CHARGE IMAGE DEVELOPMENT AND METHOD FOR SUPPRESSING FILMING USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a positively-charged toner for electrostatic charge image development that, when used for development performed by an image forming apparatus of an electrophotographic system, such as a copier and a printer, suppresses filming for a long period and can provide high-quality printed matters, where the toner can prevent the occurrence of filming during printing for a long period and provide high-quality printed matters without white streaks.;SOLUTION: There is provided a positively-charged toner for electrostatic charge image development containing (A) alumina having a circularity of 0.97 or more and 0.99 or less and a median diameter of 100 nm or more and 500 nm or less, and (B) a colorant.;SELECTED DRAWING: None;COPYRIGHT: (C)2017,JPO&INPIT
