\cleardoublepage does not work

[loudking]

Hello,all

I would like to insert an empty page after my title page,

First, I tried to use \cleardoublepage and \thispagestyle{empty}, but
the new page was not completely empty -- there is still a page number.

Next, I tried to use \thispagestyle{empty} and \mbox and \newpage.
This time it works, but I don't quite understand why \cleardoublepage
fails. Could anybody tell me the reason, please?

Here is my code.

=================================
\documentclass[a4paper, 11pt, twoside]{book}
\usepackage{graphicx}

\DeclareGraphicsRule{.jpg}{eps}{.bb}{}
\DeclareGraphicsRule{.png}{eps}{.bb}{}

\newcommand{\HRule}{\rule{\linewidth}{0.5mm}}

\begin{document}

\begin{titlepage}

%\thispagestyle{empty}

\begin{center}
\hspace{50pt}\includegraphics[scale=0.6]{./image/vu_logo.png}\\[1cm]

\textsc{\Large Master Thesis}\\[0.5cm]

% Title
\HRule \\[0.4cm]
{ \huge \bfseries blabla}\\[0.4cm]

\HRule \\[1.5cm]
\begin{minipage}{0.4\textwidth}
\begin{flushleft} \large
\emph{Author:}\\
Biu
\end{flushleft}
\end{minipage}
\begin{minipage}{0.4\textwidth}
\begin{flushright} \large
\emph{First Reader:} \\
Biu1 \\
\emph{Second Reader:} \\
Biu2 \\
\end{flushright}
\end{minipage}

%\cleardoublepage

\newpage
\thispagestyle{empty}
\mbox{}
\newpage

\end{titlepage}

I always make a new command for that:

% Start new chapter always on RHS page, so put in an additional
% blank page only when needed.
\newcommand{\clearemptydoublepage}{\newpage{\pagestyle{empty}
\cleardoublepage}}

Because \cleardoublepage issues internally a \thispagestyle{plain}
and your \thispagestyle is too late.
