Image forming agent storage container, image forming apparatus, and method of filling image forming agent

An image forming apparatus comprising:

• an image forming apparatus body;
• an image forming agent storage container that is detachably attached to the image forming apparatus body;
• and
• an image forming part that forms an image with an image forming agent stored in the image forming agent storage container, wherein
• the image forming agent storage container includes
• a container body formed with a discharge hole that is used to discharge an image forming agent,
• a rotary shaft that rotates in the container body,
• a stirring part that rotates together with the rotary shaft and stirs an image forming agent stored in the container body, and
• a conveying member that has flexibility, rotates together with the rotary shaft, and conveys the image forming agent in the container body,
• the conveying member includes
• a first end portion that comes into contact with a lower inner face of the container body and comes into contact with an upstream side and a downstream side, in a rotation direction of the conveying member, of a part where the discharge hole is formed,
• a second end portion that comes into contact with an inner face of the container body which intersect the lower inner face, and
• a slit formed between the first end portion and the second end portion, and
• a corner of the conveying member which is located between the first end portion and the second end portion is removed, and
• the slit extends from a portion from which the corner is removed toward an inside of the conveying member.

A method of filling an image forming agent, the method comprising:

• moving a stirring part and a conveying member in an image forming agent storage container so that a longitudinal direction thereof coincides with a direction along which the image forming agent is filled into a container body;
• and
• filling the image forming agent into the container body, wherein
• the image forming agent storage container includes
• a container body formed with a discharge hole that is used to discharge an image forming agent,
• a rotary shaft that rotates in the container body,
• a stirring part that rotates together with the rotary shaft and stirs an image forming agent stored in the container body, and
• a conveying member that has flexibility, rotates together with the rotary shaft, and conveys the image forming agent in the container body,
• the conveying member includes
• a first end portion that comes into contact with a lower inner face of the container body and comes into contact with an upstream side and a downstream side, in a rotation direction of the conveying member, of a part where the discharge hole is formed,
• a second end portion that comes into contact with an inner face of the container body which intersect the lower inner face, and
• a slit formed between the first end portion and the second end portion, and
• a corner of the conveying member which is located between the first end portion and the second end portion is removed, and
• the slit extends from a portion from which the corner is removed toward an inside of the conveying member.
