Abstract
An apparatus for developing a latent image recorded on a movable imaging surface, including a reservoir for storing a supply of developer material including toner particles; a donor member being arranged to receive toner particles from the reservoir and to deliver toner particles tothe imaging surface at locations spaced apart from each other in the direction of movement of the imaging surface thereby to develop the latent image thereon; and a climate system, associated with the reservoir, for maintaining the supply of developer material at a predefined temperature.
Claims16
An apparatus for developing a latent image recorded on a movable imaging surface, including:
- a reservoir for storing a supply of developer material including toner particles;
- a donor member being arranged to receive toner particles from said reservoir and to deliver toner particles to the imaging surface at locations spaced apart from each other in the direction of movement of the imaging surface thereby to develop the latent image thereon;
- and
- a climate system, associated with said reservoir, for maintaining said supply of developer material at a predefined temperature, said climate system includes a heating element and a cooling element.
An electrostatic printing machine having an apparatus for developing a latent image recorded on a movable imaging surface, including:
- a reservoir for storing a supply of developer material including toner particles;
- a donor member being arranged to receive toner particles from said reservoir and to deliver toner particles to the imaging surface at locations spaced apart from each other in the direction of movement of the imaging surface thereby to develop the latent image thereon;
- and
- a climate system, associated with said reservoir, for maintaining said supply of developer material at a predefined temperature, said climate system includes a heating element and a cooling element.
An apparatus for a developer comprising:
- a reservoir for storing a supply of developer material;
- and
- a climate system, associated with said reservoir, for maintaining said supply of developer material at a predefined temperature;
- wherein said climate system includes a heating element and a cooling element.
A method for maintaining the environment of developer material in a developer housing at a predefined set point comprising:
- sensing the temperature of said developer material;
- providing a climate system that includes a heating element and a cooling element and
- selectively activating and de-activating the heating element or the cooling element based on the temperature sensed.
