摘要： PURPOSE:To obtain images of invariably stable high quality by providing a control member provided across a specific gap from the surface of a developer carrier and a developer restraining member provided so that the gap decreases gradually toward the control member. CONSTITUTION:A diverting member 10 is positioned between an upper screw shaft 8 which conveys a developer in one direction while agitating it and a sleeve 7 and its tip part 101 forms a surface 103 in the entry direction of a developer, which is held temporarily and given the degree of freedom of movement to the screw shaft 8 and sleeve 7. The side of the diverting member on the side of the screw shaft 8 forms a concave surface so that the distance (d) from the tip of a screw part 81 for conveying is maintained, and the member on the side of the sleeve 7 is at distance (b) from the sleeve 7 and the gap decreases gradually, thereby forming a curved surface so that the gap is larger than the gap between a blade 12 and the sleeve 7, but is equal to distance (a) smaller than distance (b).

摘要： PURPOSE: To mix and agitate magnetic particles sufficiently and to stabilize the concentration of a developer by providing a control member which controls the circulation of the developer between an upper and a lower developer agitating and conveying means.
CONSTITUTION: The developer circulation control member 17 controls the circulation and conveyance of a developer nearby a magnetic pole S
3 on a developing sleeve side and also serves as a guide plate for screw shafts 8 and 9 to stabilize the conveyance and agitation of the developer. Further, a gap is formed between a developing container 7 and the control member 17 on the opposite side from the sleeve and part of the developer which is circulated and conveyed by the screw shaft 7 is guided toward the screw shaft 9. Consequently, toner supplied through a toner supply port 16 and a developer which already contains magnetic particles are mixed and agitated from the early stage.

摘要： PURPOSE:To reduce the size of a developing device and to obtain images of invariably stable high quality by controlling the movement state of a developer so that a developer becomes stable in a neither excessive nor deficient electrostatic charging state. CONSTITUTION:Toner supplied from a toner supply port 16 is agitated and conveyed while moving axially through a screw shaft 9 together with an existent developer. The mixed and agitated developer moves on a developing sleeve 71 and its circulation is controlled between a circulation control member 17 and a magnetic pole S3; and the developer on the sleeve 71 after a latent image carrier A is developed and a developer conveyed to the screw shaft 8 come together and are mixed and agitated and while part of the mixture is conveyed toward the shaft 8, the remainder passes through a circulation control member 10 and to control the layer thickness of the developer by a nonmagnetic blade 12, thereby developing the latent image on the carrier A nearby a magnetic pole N2. The developer conveyed toward the shaft 8 is conveyed in an axial direction of the shaft 8 opposite from a shaft 9, so that part of it is conveyed toward the sleeve and the remainder is conveyed toward the shaft 9. The developer on the sleeve 71 is leveled almost uniformly in the axial direction when moving axially by the shaft 8.
摘要翻译：目的：通过控制显影剂的运动状态，使得显影剂在既不过量也不充分的静电充电状态下变得稳定，从而减小显影装置的尺寸并获得始终稳定的高质量图像。构成：从现有的显影剂与墨粉供给口16一起供给的调色剂在轴向移动通过螺纹轴9的同时被搅动并输送。混合搅拌的显影剂在显影套筒71上移动，并且其循环被控制在循环控制构件17和磁极S3之间; 并且在潜像载体A被显影并且输送到螺杆8的显影剂聚集在一起并混合并搅动之后，套筒71上的显影剂在混合和搅拌的同时，一部分混合物被输送到轴8，其余部分通过循环控制构件10，并通过非磁性叶片12来控制显影剂的层厚度，从而将载体A上的潜像显影在磁极N2附近。向轴8传送的显影剂沿着与轴9相反的轴8的轴向传送，使得其一部分被输送到套筒，其余部分被输送到轴9.套筒71上的显影剂是在通过轴8轴向移动时，在轴向上几乎均匀地平坦化。
