Description of the Related Art As an image forming apparatus using an electrophotographic method, for example, a photosensitive material is irradiated with an original image to form an electrostatic latent image, and the electrostatic latent image is developed into a toner image by a developing machine. After that, there is known one in which the toner image is transferred onto a sheet, and the sheet is sent to a fixing device to fix the toner image on the sheet.As the developing machine, a developing roll is provided in a developing machine housing, There is known a developing machine using a two-component developer that conveys a two-component developer composed of toner and carrier onto a photoconductor by the developing roll to develop an electrostatic latent image into a toner image. In such a developing machine, the toner is consumed every time the developing operation is performed and the toner density of the developer is lowered.Therefore, it is necessary to supply the toner to the developing machine housing, and the toner is supplied from the toner hopper to the developing machine. ing. Such a toner hopper is provided with an agitator device for preventing toner blocking and a supply device using an auger or the like for supplying toner to the developing device housing. When a one-component developer is used,
In order to stabilize the amount of toner adhering to the developing roll, it is necessary to make the amount of toner in the developer housing constant, and for that reason, a toner hopper is provided as in two-component development and toner is supplied from there to the developer. is doing.

うな構造にしている。When the amount of toner remaining in the toner hopper becomes low, it is necessary to supply the toner. For example, a toner detection sensor is provided on the wall surface of the toner hopper, and when the amount of toner is less than a set amount, a warning is issued so that the operator can use the toner. A cartridge is used to supply toner to the hopper. As described above, the toner hopper has an agitator device and a supply device, and in order to protect these mechanisms and prevent foreign matter from entering the developing machine,
The structure is such that the replenishment port cannot be easily opened except when replenishing the toner.
