Abstract:
1. A method of replenishing a liquid toner reservoir having a liquid toner comprising carrier liquid, toner particles and charge director, the method comprising: determining a reduced amount of said carrier liquid in said reservoir; and adding, in response to said determination, a material comprising a mixture of liquid hydrocarbons including a major portion of a first liquid hydrocarbon having a first rate of evaporation, and a minor portion of a second liquid hydrocarbon having a second rate of evaporation, which first rate of evaporation at room temperature is at least an order of magnitude higher than said second rate of evaporation; wherein the first liquid hydrocarbon is present in an amount greater than 96%, and the second hydrocarbon is present in an amount between 0.5 and 4%; and wherein the first liquid hydrocarbon is present in an amount greater than 96% of weight, based upon the total weight of the mixture of liquid hydrocarbons, and the second hydrocarbon is present in an amount between 0.5 and 4% by weight, based upon the total weight of the mixture of liquid hydrocarbons.
