About に違いない
When the case marking particle に is combined with the noun 違い 'difference', and the い-Adjective ない, an expression similar to 'there is no doubt that (A)', or 'I'm sure that (A)' is created.
に違いない may be used with any verbs, い-Adjectives, な-Adjectives or nouns in their plain form.
Fun Fact
As に is marking the preceding word in this expression as an existing location (or state), 違いない is stating that no 'variance' exists within that state. This means that the literal translation of に違いない is close to 'there is no discrepancy in (A)'.
- あの人はカメラマンに囲まれている、有名人に違いない。That person is surrounded by cameramen. There is no discrepancy in that person being famous. (No reason to disbelieve)
Caution
It should be noted that 違いない is a combination of a noun and an い-Adjective, and not the negative form of the う - Verb 違う, which would be 違わない. 違いない translates as 'there is no difference', while 違わない would translate as 'it is not different'.
