Title:
TONER
Document Type and Number:
Japanese Patent JP2018141875
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a toner that is excellent in low-temperature fixability, suppress a reduction in image density and image uniformity even when images with a low printing ratio are printed for a long time, and is excellent in environmental stability.SOLUTION: A toner contains toner particles and titanate metal particles. In a grain size distribution based on the number of titanate metal particles on the surface of the toner particle, when a particle diameter at which the cumulative value from a small particle side becomes 10 number% is D10, a particle diameter at which the cumulative value from the small particle side becomes 50 number% is D50, and a particle diameter at which the cumulative value from the small particle side becomes 90 number% is D90, D50 is 10 nm or more and 90 nm or less, a grain size distribution index A represented by the ratio of D90 to D10 (D90/D10) is 2.00 or more and 10.00 or less, in a viscoelasticity measurement of the toner, the value of storage elastic modulus G' at 40°C is 1.0×10Pa or more and 1.0×10Pa or less.SELECTED DRAWING: None
