## Abstract

Flexible members for use in imaging devices which may include a non-ionic surfactant; a fluorinated surfactant; or both.

## Claims

### Claim 1

A flexible transfer member comprising a non-ionic surfactant and a fluorinated surfactant, wherein the non-ionic surfactant is present in an amount from about 0.05% by weight to about 0.15% by weight.

### Claim 2 (depends on 1)

The transfer member of claim 1, comprising plural flexible layers including a first layer and a last layer.

### Claim 3 (depends on 2)

The transfer member of claim 2, wherein said first flexible layer comprises said non-ionic surfactant and said last layer comprises said fluorinated surfactant.

### Claim 4 (depends on 1)

The transfer member of claim 1, wherein said fluorinated surfactant is present in an amount from about 0.006% by weight to about 0.06% by weight.

### Claim 5 (depends on 1)

The transfer member of claim 1, further comprising an electrical property regulating material.

### Claim 6 (depends on 5)

The transfer member of claim 5, wherein said material comprises a carbon black.

### Claim 7 (depends on 1)

An imaging device comprising the transfer member of claim 1.

### Claim 8

A flexible transfer member wherein an external surface thereof comprises a water contact angle of at least about 70°; a surface resistivity of from about 107Ω/□ to about 1013Ω/□; or both and a fluorinated surfactant.

### Claim 9 (depends on 8)

The transfer member of claim 8, wherein said fluorinated surfactant is present in an amount from about 0.006% by weight to about 0.06% by weight.

### Claim 10 (depends on 8)

The transfer member of claim 8, comprising a non-ionic surfactant.

### Claim 11

A method of making a flexible member for an imaging device, comprising applying a film-forming solution comprising a non-ionic surfactant to a mold, forming a first layer; optionally applying one or more additional film-forming solutions to said first layer, forming one or more optional layer or layers, wherein an optional layer is a last layer to firm said member; and removing said member from said mold, wherein the non-ionic surfactant is present in the first layer in an amount from about 0.05% by weight to about 0.15% by weight.

### Claim 12 (depends on 11)

The method of claim 11, wherein said first layer; when at least one optional layer is present, said last layer; or both comprise a fluorinated surfactant.
