Document Type and Number:
Japanese Patent JP3710801
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To always accurately control toner density by accurately setting a specified range of aimed toner density.
SOLUTION: A specified range of the aimed density can be determined by correctly setting a tolerable specified range of toner density TD (%) based on formula (2): TD≤{γt×Vt/Nt/(γc×Vc)}×100 using the average volume diameter Dcav_vol (μm) of a magnetic carrier and the average volume diameter Dtav_vol (μm) of the toner. Thereby, the toner density can be always exactly controlled.
