FIELD: image forming devices.

SUBSTANCE: invention relates to a delivery member for use in an image forming apparatus. Delivery member for use in an image forming apparatus comprises a support member and a first layer comprising a cross-linked silicone, a stabilising polymer comprising a polysiloxane backbone, mineral oil, wherein the first layer is disposed on the support member. Invention also relates to an image forming apparatus, comprising an image forming member having a charge-retaining surface, a charging device for applying an electrostatic charge to the image forming member, and a delivery member contacting the surface of the image forming member or the surface of the charging device, the delivery member comprising a support member and a first layer, which comprises cross-linked silicone, a stabilising polymer comprising a polysiloxane backbone, and a mineral oil and is located on the support member. Coating mixtures for making such delivery members are also described.

EFFECT: use of the invention enables to reduce printing defects and prolong the useful life of the image forming member.
