摘要： An image forming apparatus (1) includes an image carrier (31), a transfer member (36), and a light source (38). The image carrier has a photoconductive layer (31f) on a surface of the image carrier. The transfer member is configured to cause a toner image formed on the surface of the image carrier to be transferred to a transferee member (22) at a transfer position (36p) of the image carrier. The light source is configured to emit light toward the surface of the image carrier after transfer of the toner image to remove residual charges on the photoconductive layer. An effective light receiving width (EW38) of the image carrier in a width direction thereof is less than a width (W36) of the transfer member.

摘要： An image forming apparatus (11) includes a charge removing device (20) for removing the residual charge on a photosensitive film (12). The light emitted from an optical source of the charge removing device is selected from the range between the wavelengths which correspond to half of the maximum absorbance in a light absorbance characteristic of the photosensitive film (12). Since carrier generation does not occur by the light emitted by the charge removing device, the charging ability and the charge retaining ability of the photosensitive film are improved, and the image quality is significantly improved.

摘要： An image forming apparatus (1) includes a photoconductor (31Y) on which an electrostatic latent image is formed by irradiation of the photoconductor with light, a charger (32Y), a developing device (33Y), a transfer device (35Y), a charge removal execution determiner (122), and a power supply controller (700). The charger receives a superimposed voltage of a DC voltage and an AC voltage to charge the photoconductor. The developing device develops the electrostatic latent image into a toner image. The transfer device transfers the toner image to a recording medium. The charge removal execution determiner issues a charge removal command when a flow of electric charge from the transfer device into the photoconductor has occurred in an image forming outputting operation. The power supply controller applies the AC voltage to the charger for a predetermined period in a state in which the photoconductor is rotated, when the charge removal command is issued.

摘要： A blank exposure apparatus producing no black stripe on the front edge of a form, for forming a non-image area on a photosensitive body by exposing the surface of the photosensitive body to light to eliminate the charge thereon. The blank exposure apparatus includes a blank exposure lamp constituted of an array of multiple light-emitting diodes (31), a constant-voltage power supply circuit (35) for applying a constant voltage to the light-emitting diodes (31), and a switching element (36) for turning on/off the constant voltage. The control unit (110) controls the switching elements (36) when the blank exposure lamp is turned off and generates one or more pulse voltages to apply them to the blank exposure lamp, thus decreasing the amount of light from the blank exposure lamp gradually when it is turned off. An image forming device is also disclosed.
