Abstract
An apparatus which develops a latent image recorded on a flexible member. Developer material is transported into contact with the flexible member in at least two development zones. The first development zone optimizes line development and the second development zone optimizes solid area development. At least in the second development zone, the flexible member is maintained at a preselected tension so that the developer material being transported into contact is compressed and deflects the flexible member thereabout.
Claims30
An apparatus for developing a latent image recorded on a flexible member, including:
- first means, positioned closely adjacent to the flexible member defining a first development zone therebetween, for transporting a developer material into contact with the flexible member in the first development zone so as to optimize development of lines in the latent image;
- second means, spaced from said first transporting means and positioned closely adjacent to the flexible member defining a second development zone therebetween, for transporting the developer material into contact with the flexible member in the second development zone to optimize development of solid areas in the latent image;
- and
- means for maintaining the flexible member, in the region of at least the second developement zone, at a preselected tension of sufficient magnitude so that the developer material being transported into contact with the flexible member in at least the second development zone is compressed and deflects the flexible member about at least said second transporting means.
An electrophotographic printing machine of the type having an electrostatic latent image recorded on a flexible photoconductive member, wherein the improvement includes:
- first means, positioned closely adjacent to the photoconductive member defining a first development zone therebetween, for transporting a developer material into contact with the photoconductive member in the first development zone so as to optimize development of lines in the latent image;
- second means, spaced from said first transporting means and positioned closely adjacent to the photoconductive member defining a second development zone therebetween, for transporting the developer material into contact with the photoconductive member in the second development zone to optimize development of solid areas in the latent image;
- and
- means for maintaining the photoconductive member, in the region of at least the second development zone, at a preselected tension of sufficient magnitude so that the developer material being transported into contact with the photoconductive member in at least the second development zone is compressed and deflects the photoconductive member about at least said second transporting means.
