If you are using Calibre you can produce a much-improved (not perfect) epub by doing an epub-to-epub conversion with the following conversion settings:

Look&Feel page:

check box 'Remove spacing between paragraphs'

Heuristic Processing page:

check box 'Enable heuristic processing'
check box 'Detect and markup unformatted chapter hdgs...'
uncheck all other boxes

Structure Detection page:

set box 'Detect chapters at' to //h:h2

Table of Contents page:

check box 'Force use of auto-generated TOC'

Search&Replace page:

First expression (to remove surplus linebreaks)

set box 'Search Regular Expression' to the following exact text

<br />\s*<br />

box 'Replacement text' should be empty

Second expression (to remove unwanted page numbers and improve Chapter detection)

set box 'Search Regular Expression' to the following exact text

Page\s*\d+\s*

box 'Replacement text' should be empty

EPUB Output page:

make sure box 'Split files larger than' is set to 260 KB
(It needs to be done to fix a problem with the original)

There are other ways to correct this epub, but I've detailed a method which can be achieved using Calibre conversion settings only, rather than manually editing the html & css inside the epub.

Thank You For Your Detail Steps.......
I will try out later......but do i need to set back to all the normal settings after the conversion or just leave it alone.
