A toner container includes a container body, an opening, a cover, a toner discharge port, a shutter, a cylindrical structure, protrusions, and an identifier. The shutter is attached to the cover and includes a main shutter covering the toner discharge port. The main shutter moves between a closed position to close the toner discharge port and an open position to open the toner discharge port. The protrusions are on both sides of the cover and protrude in a direction orthogonal to a toner container mounting direction. The identifier is on the cover to indicate a toner color. The cylindrical structure's leading end is downstream of leading ends of the protrusions in the mounting direction. The main shutter's leading end is downstream of the protrusions' leading ends in the mounting direction when the main shutter is in the closed position. The protrusions are downstream of the identifier in the mounting direction.

Information storage system including a plurality of terminals

A developer container to store developer includes a rotator, a bearing, and a seal. The rotator includes a rotary shaft made of metal. The bearing supports the rotary shaft. The seal is made of fiber, disposed toward an inside of the developer container in the bearing, and contacts an outer circumferential surface of the rotary shaft.

Developer container, developing device, process cartridge, and image forming apparatus

A developing device configured to develop a latent image formed on a surface of an image bearer includes a rotator, a bearing, a holder, a first regulator, and a second regulator. The rotator includes a rotation shaft. The bearing supports the rotation shaft. The holder holds the bearing. The first regulator, disposed on any one of the bearing and the holder, regulates movement of the bearing such that the bearing does not fall toward one end side in an axial direction of the rotation shaft relative to the holder. The second regulator regulates movement of the bearing such that the bearing does not fall toward another end side in the axial direction relative to the holder after the bearing is attached to the holder.

Developing device and image forming apparatus containing regulated bearing

Developer container which discharges toner from a lower side and includes a box section

Apparatus and method for preventing an information storage device from falling from a removable device

Developer container having a cap with three portions of different diameters

An information storage device installed in a removable device configured to be removably installed in an image forming apparatus body, includes: an information storage unit that stores information communicated between the image forming apparatus body and the removable device; a terminal that comes in contact with a body side terminal; and a substrate that holds the information storage unit and the terminal and includes a hole configured to be engaged with a protruding section installed in the image forming apparatus body. The terminal includes a plurality of terminals each including one of a plurality of metallic plates arranged in a transverse direction thereof. An earth terminal, which comes in contact with a body side earth terminal formed in the protruding section, is formed in the hole. The hole is disposed at a position sandwiched between two metallic plates among the plurality of metallic plates.

Toner bottle

Toner container

A developer container removably installable in an apparatus body of an image forming apparatus includes a container body to contain developer, a cap connectable to the container body, the cap including a supply opening, and a flange projecting beyond an outer circumferential surface of the cap in a radial direction extending from a center of a cross section of the container body. The flange is formed along a circumference of the container body and provided between the container body and the cap.
