Passives | Agents

In most cases, the subject of an active verb (the agent) is not mentioned in the corresponding passive sentence. If it does have to be mentioned, we usually use an expression with by.

It should be noted that by is not the only word with which the agent can be introduced. After the past participles of some 'stative' verbs (verbs which refer to states, not actions) other prepositions can be used instead of by.

With is used when we talk about an instrument which is used by an agent to do an action.
