摘要： Regulating parts E, F, of a developing agent regulating member 6, are arranged opposite to a photosensitive drum 7 with respect to a line connecting the centers of a developing roll 5 having a sleeve rotating in the direction of a and a developing roll 8 having a sleeve rotating in the direction of b. Holding members 10 which are slidable on the side plate of a developing apparatus are respectively provided at both ends of the developing agent regulating member. Developing agent is supplied from developing roll 5 to developing roll 8 through a back surface of the developing agent regulating member 6.

摘要： A developing unit for an electrophotographic apparatus comprises a photosensitive body for forming a latent image thereon, a developing roll utilizing two-component developer containing toner and carrier to develop the latent image formed on the photosensitive body, a recovery roll, provided downstream of the developing roll, for recovering carrier from a surface of the photosensitive body, and at least one recess formed in an inner surface of the developing unit which is confronted with an outer cylindrical surface of the recovery roll, in such a manner that air pressure formed in the recess prevents the developer from scattering out of the developing unit.

摘要： In a multi-stage roll magnetic brush type of developing device, at least two opposite direction rotation rolls which rotate in an opposite rotation direction to that of a photosensitive body are arranged adjacently and oppositely to a photosensitive body, and at least one same direction rotation developing roll which rotates in the same rotation direction as that of the photosensitive body is arranged adjacently, oppositely to the photosensitive body and upstream of the opposite direction rotation developing rolls in the rotation direction of the photosensitive body. Thus, the path of carrying the developer by the same direction rotation developing roll and the opposite direction rotation developing rolls can be optimized. In the wide area printing at high speed, an image with stabilized printing quality can be obtained without an increase in the production cost.
