A toner container having a cylindrical shape which is detachably attachable to an image forming apparatus main body, comprising: a toner outlet (W) formed at a circumferential surface of the toner container for discharging toners contained in the toner container to a toner supplying opening of the image forming apparatus; a shutter member (32Y1a) formed at the circumferential surface of the toner container for opening or closing the toner outlet (W) together with a rotational operation of the toner container in a state where the toner container is attached to the image forming apparatus main body; a guiding member (32Y1g) formed at a part at least partially surrounding the toner outlet (W) configured to protrude from the circumferential surface of the toner container for guiding an opening or closing operation of the shutter member (32Y1a) in a circumferential direction of the toner container ; an electronic substrate (32Y1c) which performs communications between the toner container and the image forming apparatus with respect to information of the toner container and/or the image forming apparatus; and a protrusion member (32Y1d), wherein, with the opening operation of the shutter member (32Y1a), an end surface (32Y1g1) of the guiding member (32Y1g) pushes a main body side shutter which covers the toner supplying opening, and the toner outlet (W) is connected to the toner supplying opening; and wherein, when the toner container is put on an arbitrary flat surface in a state where the shutter member (32Y1a) closes the toner outlet (W), the shutter member (32Y1a) and a part of the toner container become supporting points of the toner container , characterized in that the electronic substrate (32Y1c) is disposed at the same end of the toner container as the toner outlet (W), wherein the electronic substrate (32Y1c) is positioned between the shutter member (32Y1a) and the protrusion member (32Y1d) such that the electronic substrate (32Y1c) does not contact the flat surface. a toner outlet (W) formed at a circumferential surface of the toner container for discharging toners contained in the toner container to a toner supplying opening of the image forming apparatus; a shutter member (32Y1a) formed at the circumferential surface of the toner container for opening or closing the toner outlet (W) together with a rotational operation of the toner container in a state where the toner container is attached to the image forming apparatus main body; a guiding member (32Y1g) formed at a part at least partially surrounding the toner outlet (W) configured to protrude from the circumferential surface of the toner container for guiding an opening or closing operation of the shutter member (32Y1a) in a circumferential direction of the toner container ; an electronic substrate (32Y1c) which performs communications between the toner container and the image forming apparatus with respect to information of the toner container and/or the image forming apparatus; and a protrusion member (32Y1d), wherein, with the opening operation of the shutter member (32Y1a), an end surface (32Y1g1) of the guiding member (32Y1g) pushes a main body side shutter which covers the toner supplying opening, and the toner outlet (W) is connected to the toner supplying opening; and wherein, when the toner container is put on an arbitrary flat surface in a state where the shutter member (32Y1a) closes the toner outlet (W), the shutter member (32Y1a) and a part of the toner container become supporting points of the toner container , characterized in that the electronic substrate (32Y1c) is disposed at the same end of the toner container as the toner outlet (W), wherein the electronic substrate (32Y1c) is positioned between the shutter member (32Y1a) and the protrusion member (32Y1d) such that the electronic substrate (32Y1c) does not contact the flat surface. <EOS>
