Morphology

rubber = rub (transparent) = rub + er

A 'rubber' is straightforwardly an instrument for rubbing out marks, which is a regular and recognizable -er formation from the verb 'rub'.

Etymology

Rubber meaning an eraser comes from the action rub, meaning 'to rub out', since early erasers were made from the tree gum that could remove pencil marks, so a 'rubber' is what you use to erase.
