broken images when uploaded to Box(Only Javascript)

Hello All,

I want to upload an images from BinaryString using Javascript(Not Node).

My code can uploaded text files(TXT, HTML etc).

Images(JPG, PNG, PDF etc) also can uploaded but they are broken.

I want to upload the image file without any problems.

How can I solve this problem?

The following is my code.

function Upload_Box(Binary){
	var token = "TOKEN";

	var blob = new Blob([Binary], {type: 'image/jpg'});
	//var file = new File([blob], 'test.jpg');
	var form = new FormData();
	form.append('Authorization', 'Bearer ' + token);
	//form.append('file', file);
	form.append('file', blob);
	form.append('attributes', '{"name":"test.jpg", "parent":{"id":"0"}}');

	$.ajax({
		url:"https://upload.box.com/api/2.0/files/content",
		type:"POST",
		contentType: false,
		processData: false,
		mimeType: "multipart/form-data",
		headers: {
			Authorization: "Bearer " + token,
		},
		data: form,
	}).done( function (data){
		console.log(data);
	});
}

Thanks,

Daeseung
