摘要： An improved electrophotographic copier is proposed which includes a first static charger; an image exposure unit; a second charger provided with a grid; and a developer having a developing electrode, all being arranged around a photosensitive rotatable drum.The second charger is impressed selectively with an a.c. voltage or a d.c. voltage which has an opposite polarity to that applied to the first charger. The voltage impressed to the grid has same polarity with that which is applied to the first charger. The developing agent contained in the developer includes such statically charged toner as having an opposite polarity to that of static latent images formed on the drum surface. The copier operates selectively in standard copy mode or in marginal image outline formation mode. The developing service is nevertheless carried out in the normal manner, thus employing no reverse development mode.

The corona discharge device has a wire electrode, a shield member surrounding the wire electrode including a lower portion located on the opposite side to the photosensitive member with respect to the wire electrode and a pair of side portions extending from the respective side edges of the lower portion toward the photosensitive member, and a cover member located between the photosensitive member and the wire electrode and extending downstream from the upstream side of the wire electrode with respect to the direction of transport of the paper to cover a part of the upper side of the wire electrode, the remaining part of the upper side of the wire electrode being used for transferring the toner image by corona discharge. The shield member is formed with a first opening in the lower portion for drawing air therethrough, and a second opening in one of the side portions at a position near the photosensitive member. With the above arrangement, air flows through the remaining part of the upper side of the wire electrode and also through the second opening into the corona discharge device and then flows out through the first opening by being drawn by the suction fan.
