PROBLEM TO BE SOLVED: To provide a sheet feeding device configured to make generation of electrostatic attractive force and electricity removal compatible without performing control for switching between electricity supply and the electricity removal so as to prevent productivity from deteriorating, and an image forming device.SOLUTION: A sheet feeding device comprises a first holding/conveying inner roller 202a which supplies positive and negative voltages respectively to an adsorption member 200 so that a lower slackened part 200a of the adsorption member 200 generates electrostatic attractive force when contacting a sheet. The sheet feeding device further comprises an electricity removal roller pair 250 that contacts the adsorption member 200 at an upper part 200b of the adsorption member 200 so as to remove remaining electric charges. The adsorption member 200 has an electrode pattern region which has electricity supply portions to be respectively supplied with voltages and insulated from each other in a circumference direction. Respective lengths in a circumference direction of the electrode pattern regions are set shorter than a length in the circumference direction of the adsorption member 200 at the time when the member becomes the shortest length between the first holding/conveying inner roller 202a and the electricity removal roller pair 250 which are adjacent to each other.SELECTED DRAWING: Figure 8 |
