ABSTRACT:
Dry nonelectroscopic toners comprising pigmented organic resin particles having a size distribution of 0.2 to 30 micrometers, not more than 50 percent of the particles being less than 1 micrometer surface treated with a combination of at least 1% by weight of an antistatic agent and at least 0.5% of a slip agent as described. The preparation of the toners is described. The toners are useful in colr developing positive and negative-working photosensitive elements particularly in an automatic toning machine. Improved clean-up and low stain propensity are achieved.
