摘要:
A housing of a developing apparatus is provided with a conveying member and two agitating members. A guide is provided in an inner bottom surface of the housing between two agitating members. A guide is formed into a mountain shape with wide foot portion in a cross sectional shape which is orthogonal to an axial direction of rotating shafts of the agitating members. The guide is arranged in such a manner that a gap between respective outermost portions of two agitating members, and an inner bottom surface of the housing and the guide becomes equal to or more than 1.5 mm and less than 3 mm. Further, each of two agitating members rotates in a direction from the below to the above at a position of the guide.

A housing of a developing apparatus is provided with a conveying member and first and second agitating members. A guide is provided in an inner bottom surface of the housing between the first and second agitating members. The guide has a mountain shape with a wide foot portion in a cross sectional shape which is orthogonal to an axial direction of rotating shafts of the first and second agitating members. The first and second agitating are arranged in such a manner that gaps between respective outermost portions thereof and the inner bottom surface of the housing and the guide become equal to or more than 1.5 mm and less than 3 mm. A discharge portion is provided on a downstream side of a developer agitating portion in a developer conveying direction of the first and second agitating members.

A housing of a developing apparatus is provided with a conveying member in a developer supplying and recovering portion, and with two agitating members rotating from the below to the above in portions opposed to each other in a developer agitating portion. A guide is provided in an inner bottom surface of the housing between two agitating members. A discharge portion provided with a developer discharge port is provided on a downstream side of the developer agitating portion in a developer conveying direction of the first agitating member. A suitable amount of developer can be circulated while conveying a part of an excess amount of developer in a circulating conveying path to the discharge portion and discharging from the developer discharge port. Packing and leaking of the developer within the developing apparatus and breakage of the developing apparatus can be prevented and also a good image can be obtained even if high printing images are continuously provided.

摘要:
A developing device is provided with a developer transporting member for transporting a developer containing a toner and a carrier; a toner transporting member opposite to the developer transporting member and opposite to an electrostatic latent image carrying member; a first electric field forming device, which is composed of a power source for the developer transporting member and a power source for the toner transporting member, for shifting the toner in the developer held onto the developer transporting member to the toner transporting member; and a second electric field forming device for shifting the toner held onto the toner transporting member to an electrostatic latent image on the carrying member. Operation of the first electric field forming device is controlled based on an electric current flowing in the developer transporting member power source, which is detected by a detecting block.
摘要:
The present invention relates to a toner for developing an electrostatic latent image comprising a binder resin, a colorant, a first wax, and a second wax whose kind is different from that of the first wax, wherein the toner is prepared by a kneading-grinding method and integrated domains of the first wax and the second wax are dispersed in the binder resin.
摘要:
A toner for hybrid development, comprising toner particles containing at least a binder resin and a colorant and being charged when made in friction-contact with a carrier; reverse polarity particles that are charged to polarity reversed to the charged polarity of the toner particles when made in friction-contact with the carrier, and have a number-average primary particle size in a range from 95 to 850 nm; and same polarity particles that are charged into the same polarity as the charged polarity of the toner particles when made in friction-contact with the carrier, and have a number-average primary particle size in a range from 80 to 800 nm and a shape factor in a range from 100 to 160; a developer for hybrid development containing the above toner and a carrier; and an image-forming apparatus provided with the developer for hybrid development.
摘要:
