Embodiment Construction

[0020] Next, an embodiment of an image forming apparatus according to the present invention will be described with reference to the drawings. In addition, in the following description, an XYZ rectangular coordinate system is set, and the positional relationship of each member is demonstrated referring this XYZ rectangular coordinate system. Let the specified direction in the horizontal plane be the X-axis direction, set the direction perpendicular to the X-axis direction in the horizontal plane as the Y-axis direction, and set the directions orthogonal to the X-axis direction and the Y-axis direction (that is, the vertical direction) Set to the Z-axis direction.

Abstract

An image forming apparatus of the present disclosure includes a drum unit, a development unit, a stopper, a pressing unit and an interlock device. The development unit includes a development roller that develops a toner image on the photoconductor drum. The drum unit and the development unit can be removed from the main body of the apparatus. The stopper is freely moved between a restriction position where the removal of the drum unit is restricted and a release position where the restriction of the removal of the drum unit is released. The pressing unit is freely moved between a pressing position where the development roller is pressed onto the photoconductor drum and a pressing release position where the development roller is separated from the photoconductor drum such that the pressing is released. The interlocking device interlocks the movements of the stopper and the pressing unit.

Description

technical field [0001] The present invention relates to an image forming apparatus such as a copying machine, a printer, or a facsimile apparatus. Background technique [0002] In an image forming apparatus, an electrostatic latent image is formed on an image carrier such as a photosensitive drum, the electrostatic latent image is developed with toner, and the developed toner image is transferred to a predetermined sheet. In such an image forming apparatus, the photosensitive drum and its peripheral equipment are generally formed into one or more units, and can be freely drawn out from the apparatus main body, thereby improving the efficiency of maintenance work, assembly work, and the like. [0003] Conventionally, an image forming apparatus is generally configured such that a drum unit including a photosensitive drum and a plurality of developing units that develop a latent image on the photosensitive drum and housed in a main body of the device can be drawn out in the dir...
