Benefits of technology

The present invention is not limited to the specific embodiment explained and can have various benefits. The technical effects of the invention are not limited to what is described in the embodiment.

Problems solved by technology

This trouble requires a user of the image forming apparatus to correct the stacking position of the sheets on the manual feed tray in manually feeding the sheet.
This work is very cumbersome for the user.
Accordingly, there is a problem that it is hard to set the turning range of the manual feed tray in the state in which the door is closed to be large in order to prevent the sheet from dropping from the manual feed tray in the state in which the door is opened.

Abstract

An image forming apparatus includes an apparatus body, a door supported by the apparatus body turnably within a range of a first turning angle, a sheet stacking tray supported by the door turnably within a range of a second turning angle, and a bias member whose first end is fixed to the apparatus body and whose second end is fixed to the sheet stacking tray. The bias member pulls the sheet stacking tray to the apparatus body side by a bias force generated by the door pulling the bias member when the door is opened in the state in which the sheet stacking tray is opened and reduces a turning angle of the sheet stacking tray formed with the door to be smaller than the second turning angle at least when the door is turned by the first turning angle.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to an image forming apparatus configured to form an image on a sheet.[0003]2. Description of the Related Art[0004]Heretofore, there is known such an image forming apparatus including a sheet feed portion provided at an under part the image forming apparatus and feeding a sheet, an image forming portion provided above the sheet feed portion and forming an image on the sheet fed from the sheet feed portion, and a sheet discharge portion provided at an upper part of the image forming apparatus and to which the sheet on which the image has been formed is discharged. The image forming apparatus also includes a conveying path configured to move the sheet upward and a door (side cover) permitting to expose the conveying path, when it is opened, and provided along one side surface of an apparatus body so that a jam handling process and maintenance works can be readily carried out.[0005]Still furthe...
