description	This invention is directed to an improved process for causing the development of electrostatic latent images on an imaging member comprising providing a development zone situated between a tensioned deflected flexible imaging member and a transporting member, adding conductive developer particles to the development zone comprised of toner particles and conductive magnetic carrier particles, causing the flexible imaging member to move at a speed of from about 5 cm/sec to about 80 cm/sec, causing the transporting member to move at a speed of from about 6 cm/sec to about 160 cm/sec, said flexible member and said transporting member moving at different speeds, maintaining a distance between the tensioned deflected flexible imaging member and the transporting member of from about 0.05 millimeters to about 1.5 millimeters, introducing a high electric field in the development zone, wherein the developer particles contained in the development zone are agitated, thereby providing contact between the conductive carrier particles, causing charge to rapidly flow in the direction of the deflected imaging member, said process being accomplished in the presence of a low magnetic field of less than 150 gauss, and a method of imaging utilizing such a process.
