Also, the ink manager button in the print dialog box is grayed out and I haven't installed the Postscript drivers
You are printing Composite RGB, which is converting your CMYK colors to RGB.
You need Postscript to print Composite CMYK. Even with Composite CMYK the printer might perform additional conversions, so it still might not work, but you'll have to try the PS driver to get the CMYK option.
Thank you very much. Is there any other option in Indesign besides the driver?

No because when you print to composite RGB all color gets converted to RGB then the print driver converts the RGB color back to the printer's CMYK space. So a color like 0|0|0|50 CMYK always gets converted to some CMY combination when you convert CMYK>RGB>CMYK.
It probably means your black text only pages are also using all 4 colors, which might account for the even drop in toner. Have you tried printing the text pages as Composite Grayscale?
Yes. When I'm using BW text, it uses only the Black toner. That's why in the toner counter, the black toner is less than everything else.

Are you setting the driver Output Color to Composite Gray for the text pages or leaving it at RGB?
A typical conversion from RGB black to CMYK black would be something like 70|60|60|95, so you would always be using more black.
A good test would be to print a block of 50% black as Composite Gray and Composite CMYK and look at the printed sheets under a —I'm guessing you will see CMY on the RGB sheet
