Problems solved by technology

However, if the toner tank 101 of the tank body 102 is tilted when the toner tank 101 is mounted on the apparatus body, the gear 106 will deviate from the rotation center axis.
This causes fluctuations and increases the torque of the drive body

Abstract

A powder container that is detachably installed in a container housing unit of an image forming apparatus includes a container body including an opening located at a head of the container body, and an engaging part located at a bottom of the container body, the engaging part being engaged with an engagement receiving part of the container housing unit; a drive transferring member that rotates integrally with the container body; and a lid including a discharge outlet that further discharges powder discharged from the opening of the container body, and a shutter that opens and closes the discharge outlet. A position of the powder container in the container housing unit is determined by engaging the engaging part with the engagement receiving part, and operating the lid such that the shutter opens the discharge outlet.

Description

technical field [0001] The present invention relates to a powder container detachably mounted on a body of an image forming apparatus to replenish powder such as toner consumed during image forming, and to an image forming apparatus including the same. Background technique [0002] An image forming apparatus such as a hybrid machine has at least two functions of a printer, a copier, or a facsimile. Toner is consumed while the image forming apparatus is used; thus, it is necessary to continuously replenish toner to the developing unit according to the amount of toner consumption. Toner is typically replenished using a toner container such as a toner cartridge or toner can. When the toner tank is empty, it is replaced by a new one. [0003] A cylindrical toner tank for replenishing toner into a developing unit of a conventional image forming apparatus is known, for example, as disclosed in Japanese Patent Application Publication No. 2000-338758 (hereinafter referred to as "f...
