Disclosed is a method for trapping particulate contaminants that may be found in bottles prior to filling with toner or developer. The presence of particulate contaminants, in the bottle becomes a potentially serious problem when the contaminants make their way into the developer housing and interfer with development, transfer, cleaning, and the like steps. A solution to the problem comprises coating the interior of the empty bottles with a thin film adhesive when the bottle is produced. Just prior to filling the bottle with developer, replenisher, or toner, the adhesive can optionally be activated with, for example, a short blast of steam or water mist. Particulates in the bottle then stick to the film, and become attached to the interior wall of the bottle and are thereby unable to mix with the toner replenisher or developer and not carried into the developer housing. Conventional adhesives can be used for the adhesive coating. Other materials, such as low melt polymers can be employed, for example, in flash melting, to achieve the self same effect and benefits as the adhesive. The amount of sacrificial toner, replenisher or developer adhering is quite small because of its high surface to volume ratio.
