Abstract
(EN)
The purpose of the present invention is to provide a developer cartridge capable of favorably supplying electric power to a layer-thickness-regulating blade. A developer cartridge 1 has: a housing 11 which contains toner inside; a developer roller 12; a supply roller 13 which supplies toner to the developer roller 12; a layer-thickness-regulating blade 20 which comes in contact with the peripheral surface of the developer roller 12; a developer electrode 30 which is electrically connected to the developer roller 12; and a supply electrode 100 which is electrically connected to the supply roller 13 and the layer-thickness-regulating blade 20, and which has both an electrode member 40 that is electrically connected with a rotary shaft (shaft 13A) of the supply roller 13 and that can move in a direction orthogonal to the rotary shaft of the supply roller 13, and a connection member (spring 50) that electrically connects the electrode member 40 and the layer-thickness-regulating blade 20. The electrode member 40 can move in a direction orthogonal to the rotary shaft of the supply roller 13 relative to the connection member when in contact with the connection member.

La présente invention vise à pourvoir à une cartouche de développement qui peut alimenter correctement une lame de réglage d'épaisseur de couche en énergie électrique. Une cartouche de développement (1) comprend : un boîtier (11) qui contient du toner ; un rouleau de développement (12) ; un rouleau d'alimentation (13) qui alimente le rouleau de développement (12) en toner ; une lame de réglage d'épaisseur de couche (20) qui entre en contact avec la surface périphérique de ce rouleau de développement (12) ; une électrode de développement (30) qui est connectée électriquement audit rouleau de développement (12) ; et une électrode d'alimentation (100) qui est connectée électriquement au rouleau d'alimentation (13) et à la lame de réglage d'épaisseur de couche (20), et qui possède à la fois un élément d'électrode (40) connecté électriquement à un arbre rotatif (arbre (13A)) de ce rouleau d'alimentation (13) et pouvant se déplacer dans une direction perpendiculaire à l'arbre rotatif du rouleau d'alimentation (13), et un élément de connexion (ressort (50)) qui connecte électriquement l'élément d'électrode (40) et la lame de réglage d'épaisseur de couche (20). L'élément d'électrode (40) peut se déplacer dans une direction perpendiculaire à l'arbre rotatif du rouleau d'alimentation (13) par rapport à l'élément de connexion lorsqu'il est en contact avec cet élément de connexion.
