如何删除用于章节标题的目录标题的文本格式？

Question

我在格式化目录时遇到了麻烦。我只想更改第一页，但对于其他页面，它不起作用。以下是示例：

以下是代码

\documentclass[oneside]{book}
\font\chapterTextFont = Rothdn scaled 4500 \relax
\def\splitfirstchar#1#2\sentinel{
  \chapterTextFont\uppercase{#1}\LARGE\uppercase{#2}}
\def\chapterText#1{\splitfirstchar#1\sentinel}
\usepackage{titlesec}
\titleformat{\chapter}
  {\normalfont\LARGE\bfseries}{\Huge\thechapter}{1em}{\chapterText}

\usepackage{etoolbox}
\patchcmd{\tableofcontents}
  {\chapter*{\contentsname}}
  {\chapter*{\chapterText{Contents}}}
  {}
  {}

\patchcmd{\listoffigures}
  {\chapter*{\listfigurename}}
  {\chapter*{List of Figures}}
  {}
  {}
\patchcmd{\listoftables}
  {\chapter*{\listtablename}}
  {\chapter*{List of Tables}}
  {}
  {}

\begin{document}
\begingroup
\let\clearpage\relax
\renewcommand{\contentsname}{\expandafter\chapterText{Contents}}
\tableofcontents
\listoftables
\listoffigures
