hi Surendra,
i used the below code and it works fine on IE 9, 10 & 11.
<apex:page docType="html-5.0" title="File Uploader">
    <h3>Select a file to upload as a new Chatter File.</h3>
    <input type="file" id="file" onchange="upload()"/>
    <p id="message"></p>
    <script src="//"></script>
    <script src="{!$Resource.forcetk}"></script>
    var client = new forcetk.Client();    
    function upload() {
        var file = $("#file")[0].files[0];
        client.createBlob('ContentVersion', {
            Origin: 'H', // 'H' for Chatter File, 'C' for Content Document
        },, 'VersionData', file, function(response){
            $("#message").html("Chatter File created: <a target=\"_blank\" href=\"/" + + "\">Take a look!</a>");
        }, function(request, status, response){
            $("#message").html("Error: " + status);
Please share your code, if it is fine.
I used the above code from: (" target="_blank)

Thanks, Sunil

I ran into this same problem with custom visualforce page and reason for that was that the page included apex:actionFunction component which: "actionFunctions send the page ViewState in the AJAX XmlHttpRequest and return a blob of XML (apparently using the Sarissa open source library) in the response, which has a slightly slower performance than what you'd get using JQuery's native AJAX utility methods." (quote from,category,visualforce.aspx). Seems that because of actionFunction (and possibly other VF components also) standard window.XMLHttpRequest is replaced in IE with Sarissa.js which doesn't work with ForceTK. Solution was to modify forcetk to get original xmlhttprequest if it was over-written by sarissa: 
forcetk.Client.prototype.blob = function (path, fields, filename, payloadField, payload, callback, error, retry) {
        'use strict';
        var that = this,
            url = (this.visualforce ? '' : this.instanceUrl) + '/services/data' + path,
            boundary = randomString(),
            blob = new Blob([
                "--boundary_" + boundary + '\n'
                    + "Content-Disposition: form-data; name=\"entity_content\";" + "\n"
                    + "Content-Type: application/json" + "\n\n"
                    + JSON.stringify(fields)
                    + "\n\n"
                    + "--boundary_" + boundary + "\n"
                    + "Content-Type: application/octet-stream" + "\n"
                    + "Content-Disposition: form-data; name=\"" + payloadField
                    + "\"; filename=\"" + filename + "\"\n\n",
                    + "--boundary_" + boundary + "--"
            ], {type : 'multipart/form-data; boundary=\"boundary_' + boundary + '\"'});
        var request = null;
        if(Sarissa.originalXMLHttpRequest) {
            request = new Sarissa.originalXMLHttpRequest();
        } else if (window.XMLHttpRequest) {
            request = new XMLHttpRequest();
        }"POST", (this.proxyUrl !== null && !this.visualforce) ? this.proxyUrl : url, this.asyncAjax);
