Problems solved by technology

This method cannot remove the developer unit before the toner container, so it is inconvenient
In addition, there is also a method of providing a toner conveying passage between the developer and the toner container, and taking the toner container out of the toner conveying passage, but since the toner conveying passage is provided, the corresponding Image forming device upsizing

Abstract

The present invention provides an image forming apparatus capable of easily replacing a developing device and a toner container while saving space. The image forming apparatus includes: an image carrier carrying a toner image, a developing device that supplies toner to a peripheral surface of the image carrier, a toner container that replenishes the toner to the developing device, a The paper feeding channel for feeding paper, and the box body. The case accommodates the image carrier, the developing device, and the toner container. The box includes a first face and a second face different from the first face. The toner container is taken out from the inside of the case to the outside of the case through the first surface. The developing device is taken out from the inside of the case through the second surface to the outside of the case.

Description

technical field [0001] The present invention relates to an image forming apparatus. Background technique [0002] A conventionally known image forming apparatus forms a toner image on a peripheral surface of a photosensitive drum by supplying previously prepared toner to the peripheral surface of the photosensitive drum on which an electrostatic latent image is formed. An image forming apparatus includes a developer in which toner is stored in advance. Since the developing unit has a lifespan, the developing unit needs to be replaced periodically. Therefore, in the conventional image forming apparatus, an opening and closing cover is provided on the front facing the user to take out the developing device from the inside. [0003] In addition, the image forming apparatus accommodates a waste toner container for collecting waste toner generated after transferring a toner image on a peripheral surface of a photosensitive drum to paper. The waste toner container needs to be r...
