A. Static Image Formation Block
Forms a static image on the surface of the photosensitive drum.
step 1: primary charging (charges the surface of the drum to an even negative potential)
step 2: laser beam exposure (forms a static image on the surface of the photosensitive drum)
B. Developing Block
Deposits toner over the static image on the surface of the photosensitive drum, thus turning it into a visible image.
step 3: development
C. Transfer Block
Moves the toner image from the surface of the photosensitive drum to print paper.
step 4: primary transfer (moves toner from the surface of the photosensitive drum to the ITB)
step 5: secondary transfer (moves toner from the ITB to paper)
step 6: separation (separates paper from the ITB)
D. Fixing Block
Fuses the toner image to the paper.
step 7: fixing
E. ITB Cleaning Block
Cleans the ITB by removing residual toner.
step 8: ITB cleaning (removes residual toner from the ITB)
F. Drum Cleaning Block
Removes residual toner from the surface of the photosensitive drum to prepare for the next print job.
step 9: drum cleaning (removes residual toner from the surface of the photosensitive drum)
step 10: post-exposure (prevents uneven density by evening out the surface of the photosensitive drum)

This block consists of 2 steps, at the end of which a static image is formed on the surface of the photosensitive drum.
At the end, those areas of the surface of the photosensitive drum that have not been exposed by the laser beam (dark area) retain negative charges, while those
exposed by the beam are free of negative charges. The resulting static image is not visible to the human eye and, thus, is called a static "latent" image.
