AI Technical Summary

Technical Problem

In existing color printers, multiple photosensitive elements without a separation mechanism are constantly in contact with the transfer belt during black and white printing, resulting in physical wear and electrical losses. Furthermore, the expected lifespan of the photosensitive elements is not accurately calculated, leading to premature replacement.

Method used

The controller determines the target photoreceptor that will not be exposed based on the image forming job and rotates it at a second speed lower than the preset speed. This includes reducing the rotation speed of the C, M, and Y photoreceptors during black and white printing to avoid physical wear and potential inconsistency. The expected lifespan calculation is optimized in conjunction with the lifespan calculation unit.

Benefits of technology

It effectively reduces physical wear and electrical losses of the photosensitive element, extends the expected lifespan of the photosensitive element, avoids unnecessary replacements, and improves the lifespan of the printer.

Abstract

The present application provides an image forming apparatus, an image forming method and a medium for solving the problem that the prior art fails to properly maintain the service life of a printer. The image forming apparatus of the present application comprises: a plurality of photosensitive bodies; a driving device for driving the plurality of photosensitive bodies to rotate; an exposure device for forming an electrostatic latent image by image exposure on at least one of the plurality of photosensitive bodies; a plurality of developing devices for performing development on a plurality of latent images formed on the plurality of photosensitive bodies by different color toners, so that the plurality of photosensitive bodies carry toner images; an intermediate transfer body, which is in contact with the plurality of imaging components at the same time, for transferring the toner images; and a controller configured to determine a target photosensitive body on which exposure is not performed according to an image forming job to be processed, and make the target photosensitive body rotate at a second speed lower than a preset first speed by the driving device. The present application can achieve the technical effect of preventing the expected service life of the image forming apparatus from being reduced.
