摘要： Example embodiments include a driving device having: a plurality of vibrating members that may vibrate when the vibrating members are driven; and a holding part that may hold the vibrating members. The holding part may include a first member with which one or more of the vibrating members may be brought into contact, and a second member with which one or more of the vibrating members may be brought into contact. The first member and the second member may be partially coupled to each other. A grounding member for electrically grounding a member held by the holding part may be brought into contact with one of the first member and the second member that is more difficult to vibrate.

摘要： A sheet conveying device, which is included in an image forming apparatus and an optional device attachable to the image forming apparatus, includes a sheet container, a sheet feeder, a separator, a guide, and a projection. The sheet container loads multiple sheets. The sheet feeder feeds a sheet out of the multiple sheets in the sheet container. The separator separates the sheet from another sheet fed together with the sheet. The guide having a guide surface to guide the sheet passing the separator such that the sheet is fed in a predetermined sheet conveying direction. An upstream end in the sheet conveying direction of the guide surface of the guide is located lower than a downstream end in the sheet conveying direction of the separator. The projection is disposed facing the separator at the upstream end in the sheet conveying direction of the guide surface.
