1. An image forming apparatus comprising:
an apparatus main body that includes an openable/closable cover member and an internal space;
an image carrier located in the apparatus main body, the image carrier having a circumference surface on which an electrostatic latent image is formed by rotationally driving the image carrier;
a developing device that includes a developer replenishment port to which a developer is replenished and a mounting portion, the developing device being mounted at a developing position with the cover member open, the developing position being opposed to the image carrier in the internal space, the developing device supplying the image carrier with the developer;
a developer housing container that includes a developer discharge port from which the developer is discharged and a storage unit, the developer housing container internally housing the developer, the developer housing container being mountable to the internal space selectably by a first mounting aspect or a second mounting aspect, the first mounting aspect mounting the developer housing container to the internal space integrally with the developing device with the cover member open, the developer housing container being preliminary mounted to the mounting portion of the developing device such that the developer discharge port communicates with the developer replenishment port, the second mounting aspect mounting the developer housing container to the mounting portion of the developing device preliminary mounted to the internal space with the cover member open such that the developer discharge port communicates with the developer replenishment port; and
a connector located opposed to the developer housing container in the apparatus main body, the connector being electrically connected to the storage unit in the developer housing container, the developer housing container being mounted to the internal space in the first mounting aspect or the second mounting aspect,
wherein the storage unit includes a substrate, a first ground terminal, and a first input/output terminal exposed outside at the substrate,
the connector includes:
a connector housing that includes an opening and an end edge, the end edge defining one side portion of the opening; and
elastically deformable second ground terminal and second input/output terminal projected from the opening, the second ground terminal and the second input/output terminal contacting the first ground terminal and the first input/output terminal, respectively, by mounting the developer housing container to the internal space,
the second ground terminal and the second input/output terminal each abut the end edges on the connector housing with elastic force, the abutment regulating a maximum amount of projection of the second ground terminal and the second input/output terminal with respect to the opening,
the end edges include a first end edge and a second end edge, the first end edge defining the side portion of the opening, the second end edge being opposed to the second ground terminal, the second end edge having a shape formed by partially notching the first end edge, and
abutting the second ground terminal with the second end edge and abutting the second input/output terminal with the first end edge configure the maximum amount of projection of the second ground terminal with respect to the opening larger than a maximum amount of projection of the second input/output terminal with respect to the opening.
