Abstract: In a xerographic development system in which an AC field is set up in a gap between a donor member and the photoreceptor to develop an electrostatic latent image, a series of tests are performed to ascertain that the width of the gap is within a suitable range. In test mode, various DC and AC biases associated with the field are systematically altered, and the reflectivities of resulting test images are read. Based on these reflectivity readings, it can be determined if the gap is too wide, such as to cause poor print quality, or too narrow, such as to cause arcing.

Abstract: PROBLEM TO BE SOLVED: To provide a developing device with improved edge enhancement of a developed image. SOLUTION: The hybrid jumping developing device 34 is equipped with a toner supply source 42, a donor roll 36 spaced from a charge retentive surface and feeding toner to an area near to the charge retentive surface from the supply source 42, a device 114 producing in the vicinity of the charge retentive surface a toner cloud for developing an electrostatic latent image on the charge retentive surface by applying an alternating current directly to the roll 36 and generating alternating electrostatic field, and an edge enhancement scavenging (sweeping) device 200 existing near the roll 36 and redistributing the toner on the developed electrostatic latent image. The device 200 generates electrostatic field between the developed latent image and the device 200 and scavenges the toner from the developed latent image so as to improve the edge enhancement of the image.
