IMAGE FORMING APPARATUS

摘要

The image forming apparatus includes a process unit, a latent image writer, a power source, and a controller. The process unit is detachably attachable relative to the image forming apparatus and includes, as a single integrated unit, a latent image bearing member to bear a latent image on a surface thereof, a charging device to charge the surface of the latent image bearing member, and a development device to develop the latent image with toner. The controller causes the power source to output a charging bias at a predetermined target level supplied to the charging device. The process unit includes a first storage device to store correction information for calculating the predetermined target level of the charging bias in accordance with a combination of the latent image bearing member and the charging device. The controller corrects the predetermined target level based on the correction information in the first storage device.

1. An image forming apparatus, comprising:
a process unit detachably attachable relative to a main body of the image forming apparatus, the process unit including, as a single integrated unit,
a latent image bearing member to bear a latent image on a surface thereof,a charging device to charge the surface of the latent image bearing member, anda development device to develop the latent image on the surface of the latent image bearing member with toner to form a toner image; a latent image writer to write the latent image on the surface of the latent image bearing member charged by the charging device; a power source to output a charging bias supplied to the charging device; and a controller operatively connected to the power source to cause the power source to output the charging bias at a predetermined target level, the process unit further including a first storage device to store correction information for calculating the predetermined target level of the charging bias in accordance with a combination of the latent image bearing member and the charging device, the controller correcting the predetermined target level based on the correction information stored in the first storage device.
