Can I use an iMac Bluetooth Keyboard with an iPad1 or iPad2?

Can I use an iMac Bluetooth Keyboard with an iPad1 or iPad2?

Do I need a keyboard that state's it is for ipad? Or can I use the Apple iMac Bluetooth keyboard for my ipad?

I don't see anywhere on the Apple iMac keybaord box that states it is compatible.

I find the 3rd party ipad keyboards to be flimsy in construction.

Thanks
