JB/T 9443-2026 is a technical specification for dry insulating magnetic monocomponent negative toner used in the electrostatic copying process. This type of toner works without a separate carrier: each particle is magnetic and electrically insulating, and it carries a negative charge when used. The document is a product standard for this toner.

It is used by toner manufacturers, by makers of copying machines designed for monocomponent toner, by testing laboratories and by purchasers of copier consumables. It is a voluntary standard, as shown by the /T in its code. It was approved and issued by the Ministry of Industry and Information Technology on 1 June 2026 and takes effect on 1 December 2026. It replaces JB/T 9443-2013.
