Abstract
A method and device for controlling toner transfer during the formation of a toner image within an image forming device is described herein. One exemplary image forming device includes a toner reservoir that stores toner of a first color, a developer member that receives toner from the toner reservoir, a photoconductive member proximate the developer member that receives toner from the developer member, and a driver. While rotating the photoconductive member, the driver selectively rotates the developer member based on a color content of the image. For example, the driver does not rotate the developer member while rotating the photoconductive member when the toner image being formed lacks the first color. Alternatively, the driver lows the rotational speed of the developer member while rotating the photoconductive member when the toner image being formed lacks the first color.
