Image forming apparatus

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.
