Detack enhancement for electrostatographic document copiers/printers

An electrostatographic copier/printer comprising:

• an image member;
• means for selectively image-wise exposing a frame of said image member to create an electrostatic latent image;
• means for contacting the image member with toner developer so as to produce a toner image according to the electrostatic latent image if the frame has been image-wise exposed and to leave a small amount of background toner uniformly deposited if the frame has not been image-wise exposed;
• means for transferring the toner from the image member to a receiver sheet;
• and
• means for separating the receiver sheet and transferred toner from the image member.

A process for producing electrostatographic images on a copier/printer having an image member, said process comprising:

• selectively image-wise exposing a frame of said image member to create an electrostatic latent image;
• contacting the image member with toner developer so as to produce a toner image according to the electrostatic latent image if the frame has been image-wise exposed and to leave a small amount of background toner uniformly deposited if the frame has not been image-wise exposed;
• transferring the toner from the image member to a receiver sheet;
• and
• separating the receiver sheet and transferred toner from the image member.
