Title:
A development device and an image forming device using this
Document Type and Number:
Japanese Patent JP6024089
Kind Code:
B2
Abstract:
A development device includes a developer carrier; a layer-regulating rotating member that faces the developer carrier with a gap therebetween and rotates in a direction following the rotation of the developer carrier while regulating the thickness of a layer of developer on the developer carrier; a development controller that controls, during development, the developer carrier and the layer-regulating rotating member to rotate at respective predetermined speeds and develops an electrostatic latent image on an image carrier with the developer; and a discharge controller that controls, while development is stopped, the developer carrier to rotate at a predetermined speed while controlling the layer-regulating rotating member to rotate at a speed that changes intermittently such that the amount of developer passing the layer-regulating rotating member changes and any foreign matter and aggregates in the developer are discharged together with the layer of the developer whose thickness is changed on the developer carrier.
