Abstract

An image forming apparatus includes an image forming portion, a development voltage power supply, a current detection mechanism, and a control portion. The image forming portion includes an image carrying member having a photosensitive layer on its surface and a developing device that has a developer carrying member, opposite the image carrying member, carrying two-component developer containing magnetic carrier and toner, and that attaches toner to an electrostatic latent image on the image carrying member, forming a toner image. The development voltage power supply applies a development voltage at least containing a direct-current voltage to the developer carrying member. The current detection mechanism detects, with the development voltage applied to the developer carrying member, a development current between the developer carrying member and the image carrying member. The control portion adjusts image density of a halftone image according to a development current when the halftone image is formed.

Dependent claims

An image forming apparatus comprising:

an image forming portion including:
an image carrying member having a photosensitive layer formed on a surface thereof;
and
a developing device having a developer carrying member that is disposed opposite the image carrying member and that carries two-component developer containing magnetic carrier and toner, the developing device attaching the toner to an electrostatic latent image formed on the image carrying member to form a toner image;
a development voltage power supply that applies a development voltage at least containing a direct-current voltage to the developer carrying member;
a current detection mechanism that detects, when the development voltage is applied to the developer carrying member, a development current passing between the developer carrying member and the image carrying member;
and
a control portion that controls the image forming portion and the development voltage power supply,
wherein
the control portion detects, using the current detection mechanism, the development current when a halftone image is formed as the toner image and adjusts image density of the halftone image based on a detection result.
