摘要:
The present invention provides an electrostatic latent image developer used in an image forming apparatus including: an image holding member; a charging unit; a latent image forming unit; a developing unit which stores the electrostatic latent image developer and includes a developer holding member, wherein the developing unit develops the electrostatic latent image formed on the image holding member by bringing a magnetic brush, which is formed on a surface of the developer holding member by the electrostatic latent image developer, into contact with the image holding member, to form a toner image; a transfer unit; a cleaning unit; and a lubricant applying unit, wherein the electrostatic latent image developer contains a toner having a 50% integrated volume particle diameter of from 3.0 to 6.0 μm, and a carrier having a mean magnetization of 5.0×10−16 to 4.0×10−15 AM2/particle in an applied magnetic field of 1 kilo-oersted.

摘要:
A developing device includes a developer carrier that holds a developer on a surface thereof, rotates around a rotation axis, and supplies the developer to an image carrier at a facing portion at which the developer carrier faces the image carrier; a transport member that transports the developer in a transport direction along the rotation axis while supplying the developer to the surface of the developer carrier; and a guide member that includes a guide portion that guides, toward downstream in the transport direction, the developer that has passed the facing portion without being supplied to the image carrier, the guide member making an amount of the developer that reaches the transport member on an upstream side of the guide portion in the transport direction be smaller than an amount of the developer that reaches the transport member in on a downstream side of the guide portion.
摘要:
A developing device includes first and second developer carriers facing each other in a facing region, a regulating member that regulates a layer thickness of developer, and a separation member. The first and second developer carriers respectively include first and second magnetic members that are respectively magnetized with first and second facing magnetic poles having opposite polarities. The separation member separates the developer so that the developer is supplied toward the first and second developer carriers. The separation member is disposed such that distances between the separation member and the first and second developer carriers are the smallest in a region in which a magnitude of a combined magnetic field of the first and second magnetic poles locally decreases as compared with a case where at least one of the first and second developer carriers is independently disposed due to interaction between the first and second facing magnetic poles.
