項記載の現像装置。[Scope of Claim for Utility Model Registration] (1) A hopper equipped with a toner supply roller, and a developer conveyance sleeve that has a magnet with a plurality of magnetic poles inside and rotates in the opposite direction to the rotation of the photoreceptor drum. , an agitation roller that rotates in the same direction as the developer conveyance sleeve and is equipped with a large number of agitation blades for performing frictional charging of the toner particles and uniform mixing of the toner and the carrier; a brush cutting plate for regulating the height of the magnetic brush to be formed; an upper guide plate located above the stirring roller; and a developer flow guide mechanism located below the conveying sleeve and the stirring roller. In the two-component developing device comprising: A guide plate (first guide plate) that is oriented at an acute angle or an obtuse angle with the partition plate (first guide plate) and a guide plate (second guide plate) that is provided above the partition plate. The first guide plate and the second guide plate are provided substantially parallel to each other, and the orientation directions of the first guide plate and the second guide plate are in a positional relationship such that they intersect with each other. A two-component developing device characterized in that a plurality of developer scraping protrusions are provided at predetermined intervals at positions. (2) A request for registration of a utility model characterized in that the magnet inside the developer conveying sleeve is arranged such that magnetic poles of the same polarity are adjacent to each other in an upper part of the developer flow guide mechanism. range 1
Developing device as described in section.
