A toner cartridge according to one example embodiment includes a housing having a toner reservoir. An outlet is positioned on the housing for exiting toner from the toner cartridge. An insert is selectably installable in the toner reservoir. The insert separates a first portion of the toner reservoir that is in fluid communication with the outlet from a remainder of the toner reservoir when the insert is installed in the toner reservoir providing a reduced capacity toner reservoir in the first portion of the toner reservoir.

A toner release coating may be applied to a toner regulating member such as a doctor blade. The toner release coating may reduce toner adhesion at a doctoring pre-nip location of the doctor blade. The toner release coating may be formed from a mixture of lubricating particulate and polymeric binder resin in a liquid carrier.

The present disclosure relates to a surface energy reduction material in the form of a topcoat or additive to a coating that may be applied to a toner regulating member such as a doctor blade which may reduce toner build-up about a nip region, pre-nip region, and/or post-nip region. The surface energy reduction material may be include any material having a surface energy of less than or equal to 35 dynes/cm, for example, between 15-30 dynes/cm, including all values and ranges therein. The surface energy reducing materials may include any material that provides a 25% or more reduction of the surface energy of the doctor blade compared to an untreated doctor blade, for example, greater than or equal to 50% reduction or greater than or equal to 75% reduction, including all values and ranges therein.

Doctor blade surface energy modification

The present disclosure relates to the use of radiation cured coatings that may be used in a device within an image forming apparatus. The coating composition may include a reactive oligomer capable of radiation curing having a number average molecular weight (Mn) of greater than 1500. A reactive diluent may then be combined with the reactive oligomer, which diluent is also capable of radiation curing and which has a Mn of less than or equal to 1500. The reactive diluent may be present at a level of less than fifty percent by weight of the coating composition. The coating composition may be present at a solids level of 90-100%.
