TONER, TONER CARRYING APPARATUS AND IMAGE FORMING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an image forming apparatus in which toner clogging in a sucking tube is suppressed even when a toner carrying system using both of toner sucking and air feeding to a toner container is employed.

SOLUTION: The image forming apparatus is constituted to use the toner having one of the following properties. They are: (1) the toner shows ≤30 G [N/m2] maximum shearing stress τmax when 16 G [N/m2] vertical stress is added in a shear testing machine 100; and (2) the toner shows ≤50 G [N/m2] uniaxial fracture stress fc measured by a uniaxial fracture stress measuring method using the above shear testing machine 100.
