Problems solved by technology

However, if the height dimension of the sealing member on the back of the blade is reduced, the width of the sealing member in the height direction on the back of the blade becomes smaller, and the sealing performance is reduced, which is prone to inconveniences such as leakage of the developer due to spreading from the back of the blade.

no. 1 Embodiment approach

[0111] Also, in this example, the squeegee inner seal 87 is attached to the leaf spring member 57 by the double-sided tape 90, the squeegee assembly 40 with the squeegee inner seal 87 is assembled to the squeegee assembly part 46, and the double-sided tape 90 is attached to After the front assembling part 48 of the scraper assembly part 46 is partially pasted on the inner seal 87 of the scraper with respect to the double-sided tape 90, the scraper assembly 40 may be assembled to the scraper assembly 46. First embodiment: Second example

[0112] Picture 11 It is a front view showing another example of the doctor blade assembly 40. And, the parts corresponding to each part are Picture 11 The same reference numerals are assigned, and the description thereof will be omitted below.

[0113] At that Picture 11 In the scraper assembly 40 shown, on the back of the leaf spring member 57, the entire area on the lower end side of the leaf spring member 57 with respect to the reinforcing ...

no. 2 Embodiment approach

[0120] In this example, as the elastic adhesive 150, Super X (Japanese: スパ-X, manufactured by Quick-acting Adhesive Co., Ltd. (manufactured by Semeden Co., Ltd.), a registered trademark) was used. Adopt the method of bonding the leaf spring part 57 of Super X, the reinforcing plate 59 and the seal 87 in the scraper, preferably as Figure 16 As shown, after applying Super X to both ends of the reinforcing plate 59 in the longitudinal direction, it is left for ten minutes and then bonded separately in a semi-dry state. Therefore, after applying Super X to the both ends of the reinforcing plate 59 in the longitudinal direction and leaving it for a few minutes (for example, 2 minutes), compared with the case where the doctor blade assembly 40 and the blade inner seal 87 are bonded to each other, the developing cartridge 26 It becomes easy to peel off during reuse, which can improve its reusability. The second embodiment: the first example

[0121] Such as Figure 17 As shown, in the de...

Abstract

In the invention, a scraper back sealing member is gripped between a plate spring member of a scraper unit and a scraper assembling member. The scraper back sealing member integrally has: side parts which extends up and down on two end parts in the length direction of the plate spring member, and a connecting part which is arranged on the middle part in the length direction of the plate spring member to connect the two side parts. An upper sealing member for sealing is gripped between an opening part of a frame body, and an upper assembling part which extends in the length direction of the opening part and has a width in the fore and back direction, and the extending part of the anti-bending member of the scraper unit.

Description

Technical field [0001] The invention relates to a developing device, a processing box, an imaging device provided with a developing device and a processing box, and an assembling method of the developing device. Background technique [0002] In imaging devices such as laser printers, an electrostatic latent image is formed on the surface of a photosensitive drum and the developer is supplied to the electrostatic latent image from the developing device, thereby carrying the developer image on the surface of the photosensitive drum. Then, by printing the developer image on the paper, the image is formed on the paper. [0003] The developing device has: a frame with an opening to the photosensitive drum; a developing roller that carries the developer contained in the frame; and a blade (layer) for regulating the layer thickness of the developer carried on the developing roller. Thick restriction member). The developing roller is rotatably supported on t...
