Title:
TONER SET
Document Type and Number:
WIPO Patent Application WO/2021/172517
Kind Code:
A1
Abstract:
The present invention provides a toner set and an image forming method which provide excellent gradation and color reproducibility to an image including multiple colors and high printing durability against continuous printing, and which enable printing of full-color images. When a toner having one color, selected from a group of toners having various colors included in the toner set, is defined as a first toner, and a toner having another color is defined as a second toner, the internal friction angle θ1 (°) of the first toner and the internal friction angle θ2 (°) of the second toner satisfy relationships represented by the formulae (1) and (2). Formula (1): θ1<θ2, formula (2): 1°≤θ2-θ1≤3°. An image including multiple colors is formed by transferring a first image developed by using the first toner and a second image developed by using the second toner onto a recording material or a transfer medium in this order.
