Claim Text:
1. An image forming apparatus, comprising: an image forming apparatus body; a cassette attaching section having a media supplying roller that supplies media to the image forming apparatus body; a release portion; a media cassette detachably installed in the cassette attaching section, the media cassette including: an urging portion urging the plate holding portion, the urging portion urging the plate holding portion to a position engageable with the loading plate when the media cassette is located outside the cassette attaching section, the release portion pushing the plate holding portion against an urging force of the urging portion, the release portion moving the plate holding portion away from the position engageable with the loading plate; the projecting portion and the release portion of the image forming apparatus body entering into a state electrically connecting with each other at a position lower than the loading plate when the media cassette is inserted into the cassette attaching section, the projecting portion and the release portion of the image forming apparatus body being in an electrically disconnecting state when the support section of the media cassette is located outside the cassette attaching section, wherein, when the media cassette is inserted into the cassette attaching section while the media cassette is resisting against the pushing up force of the pushing up member, the projecting portion and the release portion enter into the connecting state while the media and the media supply roller are separated from each other, wherein, when the projecting portion and the release portion enter into the connecting state, the static electricity of the media is released to the grounding point through the projecting portion and the release portion, and wherein, when the media cassette moves further into an inserting direction after the projecting portion and the release portion enter into the connecting state, the loading plate comes closer to the media supplying roller by the pushing up force of the pushing up member, and a second ground conducting route including a ground portion provided in the image forming apparatus body, the ground portion contacting the media conveyed with the media supplying roller after the media cassette is installed in the cassette attaching section, the ground portion discharging electrostatic charges accumulated on the conveyed media.
