摘要： An electrophotographic printing device using a light source for emitting predetermined light and a photosensitive material on which an electrostatic latent image is formed by the light from the light source. The electrophotographic printing device has a memory for storing density control information on light intensity of the light source and density of an image formed on a printing medium, and a light intensity controller for controlling the light intensity of the light source based on the information in the memory. The density control information stored in the memory is determined from a relationship between the density of the image to be formed and potential of the electrostatic latent image, and a relationship between the potential of the electrostatic latent image and the light source.

摘要： An image forming apparatus includes an image holding member, a visible image detecting unit, a shielding part, a conveying passage, and a medium contact part. The visible image detecting unit includes a detecting part and detects a visible image, and the detecting part is disposed to face the image holding member. The shielding part is supported to be movable between a shielding position where the detecting part is shielded, and a detection permitting position where the detecting part is exposed. The medium contact part is supported to be movable between an entry position where the medium contact part enters a conveying passage, and a medium contact position where the medium contact part comes into contact with a medium and recedes from the entry position. The image forming apparatus moves the shielding part while interlocking with the movement of the medium contact part.

摘要： In a control method for a transfer roller, after detecting an interval between a first recording medium and a second recording medium following the first recording medium, one of a first control mode and a second control mode is selected. If the first control mode is selected, and if the interval is not longer than a time period corresponding to one turn of the transfer roller, the transfer roller is kept at a first voltage until a second transfer to the second recording medium is completed. If the second control mode is selected, and if the interval is longer than the time period corresponding to one turn, the transfer roller changes between the first voltage and a second voltage which are opposite in polarity, before the second transfer to the second recording medium.
