Answer 1

attach can set Buffer.
But, you need to use filename option.

this works well.

var request = require('superagent');
request.get('https://example.com/image.png')
  .end((err, res) => {
    // Here i want send responsed image to another server
    console.log(err, res.body); // body is Buffer
    request.post('http://upload-example.com')
      .attach('image', res.body, {filename: 'test.png'})
      .end((err, res) => {
        console.log(err, res.statusCode);
      });
});
