Embodiment Construction
[0052] FIG. 1 is a cross-sectional view showing an internal structure of an image forming apparatus according to a first embodiment. First, the basic configuration of the image forming apparatus 100 will be described. In FIG. 1 , an image forming apparatus 100 has four process cartridges 400Y, 400M, 400C, and 400K for generating toner images of yellow, magenta, cyan, and black (hereinafter referred to as Y, M, C, and K). . It uses Y, M, C, and K toners of different colors as an image forming material, but has the same structure except for that, and is replaced when the service life is reached. Taking the process cartridge 400Y for generating a Y toner image as an example, as shown in FIG. Wait. The process cartridge 400Y as an image forming unit can be attached and detached from the main body of the image forming apparatus 100 , and consumable parts can be replaced at one time.
[0053] The charging device 406Y uniformly charges the surface of the photosensitive drum 401Y ...

A sheet conveying apparatus includes a pair of rollers; a conveying unit that conveys a sheet by holding in a nip portion, the nip portion formed by a pair of rollers as a rotating unit such that one of the pair of rollers contacts and pressurizes the other roller; a pressure lever of which a fixed edge is oscillatably supported by a immovable portion, the pressure lever including an oscillating edge, the oscillating edge of the pressure lever being capable of contacting a supporting shaft of the pressure roller; an oscillating lever of which a fixed edge is oscillatably supported by the pressure lever in the oscillating edge side, the oscillating lever including a plurality of oscillating edges around the fixed edge; and an elastic unit that is latched between the fixed edge of the oscillating lever and the immovable portion, and biases the oscillating lever towards the one of the pair of rollers. A position of the fixed edge of the oscillating lever, from among positions at which an end of the elastic unit is latched on, is capable of being changed in a state of being deviated from a position before oscillating based on an oscillating position of the oscillating lever separately from an oscillation of the fixed edge.
Description
technical field [0001] The present invention relates to a sheet conveying device and an image forming apparatus, and more specifically, to a pressurizing mechanism of a roller pair used for sheet conveying. Background technique [0002] In recent years, it has been well known that in an image forming apparatus adopting an electrophotographic method or an electrostatic method, if an electrostatic latent image corresponding to an image signal is formed on a similarly charged latent image carrier, that is, a photoreceptor, then the image forming apparatus supplied from the developing device will Toners visualize the electrostatic latent image. [0003] After the toner image carried on the photoreceptor is transferred to recording paper as a recording medium, it is fixed on the sheet P under the action of melting and soaking by heat and pressure by a fixing device. As described in Japanese Patent No. 3243143, there is disclosed a fixing device having a heating roller as a fixin...
