Abstract:
1. An image forming apparatus, including: a photosensitive member having a photosensitive member surface; a charging apparatus configured to, when applied with a charging voltage, charge the photosensitive member surface to form a charged surface; an exposure apparatus configured to expose the charged surface to form an electrostatic image; a developing apparatus configured to, when applied with a development voltage, attach a developer to the electrostatic image and develop the electrostatic image as a developer image; an environment measuring apparatus configured to measure information regarding temperature; a time information obtaining apparatus configured to obtain information regarding a photosensitive member rotation time, which represents a time during which the photosensitive member is rotated, and information regarding a photosensitive member stop time, which represents a time during which the photosensitive member is stopped; and a control apparatus configured to control an image formation condition, wherein the control apparatus has a control mode for controlling, during formation of an image, the image formation condition based on: (i) the information regarding temperature measured by the environment measuring apparatus, (ii) the image formation condition at a time when the information regarding temperature is measured by the environment measuring apparatus, (iii) information regarding a photosensitive member rotation time as obtained after the time when the information regarding temperature is measured by the environment measuring apparatus, and (iv) information regarding a photosensitive member stop time as obtained after the time when the information regarding temperature is measured by the environment measuring apparatus.
