Toner and developer providing offset lithography print quality

摘要

A method of forming a toner having controlled properties for use in a developer composition finding particular use in a hybrid scavengeless development scheme includes feeding at least one binder and at least one colorant into a mixing device at a feed ratio, upon exit of the mixture from the mixing device, monitoring one or more properties of the mixture with at least one monitoring device, wherein if the monitoring indicates that the one or more properties being monitored is out of specification, removing the monitored mixture from the method and adjusting the feed ratio by adjusting the feeding of the at least one binder or of the at least one colorant, thereby retaining in-specification mixture in the method, grinding the in-specification mixture, optionally together with a portion of one or more external additives to be added to the mixture, classifying the ground in-specification mixture, and mixing the classified in-specification mixture with one or more external additives to obtain the toner having controlled properties. Use of the toner obtained in a developer in a hybrid scavengeless development apparatus enables images to be achieved with properties similar to that achieved in offset lithography.
