And Turkey controller to output the image signal, Latent before the effective image areas of the latent image bearing member by that reciprocally scans along the modulation light in a predetermined direction by the deflection mirror surface while modulating the intensity of light based on the image signal output from Kiko controller An engine unit having an exposure unit for writing an image; E Bei an engine controller for outputting a write request signal for requesting an output of the image signal to the exposure unit before Kiko controller, wherein the exposure unit is one scannable scanning range along the predetermined direction at the position of the end portion side, and at a position outside the scanning range corresponding to the effective image area of the latent image bearing member, wherein the one end portion side of the other scannable scanning range along the predetermined direction includes a sensor for outputting a detection signal by detecting the outgoing light to said engine controller to be scanned on the end side, the engine controller outputs a write request signal based on the detection signal, before Kiko controller is recovery for performing backward write a backward scan of the forward data and light for performing forward write the forward scan of the light before the write request signal from said engine controller is input Create and use data, said forward write an image signal for backward writing corresponding to the forward writing image signal and the return data corresponding to the forward data in response to the input of the write request signal An image forming apparatus that outputs an image signal for image use and an image signal for backward writing in order . The engine controller, said a time from the output time has elapsed first waiting time detection signal, the detection signal long second waiting time than the first waiting time from an output time of from the sensor from the sensor the point when the elapsed, Outputs the write request signal, before Kiko controller, the forward in response to the input of the write request signal of the first waiting time elapse of the two write request signal And outputting a backward write image signal corresponding to the return data in response to an input of a write request signal when the second waiting time has elapsed. The image forming apparatus according to 1. The engine controller, than the outputs a forward for the write request signal after the lapse of output time point of the detection signal of the first waiting time, the said first waiting time from an output time point of the detection signal from the sensor from the sensor also it outputs the backward write request signal after a long second standby time, before Kiko controller is forward writing image signals corresponding to the forward data in response to an input of the forward path for the write request signal The image forming apparatus according to claim 1, wherein the image forming apparatus outputs a return path writing image signal corresponding to the return path data in response to the input of the return path write request signal. The engine controller, after the elapse of a first waiting time from the output time of the detection signal from the sensor, and the time interval from the start time of the forward write to the start time of the return pass write and output before Kiko controller and the length of the second waiting time showing a prior Kiko controller may output an image signal for the forward writing corresponding to the forward data in response to the input of the write request signal and, an image forming apparatus according to claim 1, wherein outputting the backward write image signals the corresponding return data after a lapse of the second waiting time from the output start of the forward writing image signals. 5. The engine controller according to claim 2, wherein the engine controller corrects the writing position of the latent image in the predetermined direction by adjusting a length of the first and second standby times before outputting the write request signal. An image forming apparatus according to claim 1. The latent image carrier; The exposure unit; A developing unit for developing a latent image formed on the latent image carrier to form a toner image; 5. The image forming apparatus according to claim 2, wherein for each of a plurality of different colors, a toner image formed on each latent image carrier is superimposed to form a color image. 5. the Bei example a storage unit for storing a positional deviation amount of the toner image as a predetermined amount of the resist in a predetermined direction, adjust the length of the predetermined amount of the resist wherein the first and second waiting time based on among the plurality of colors Image forming apparatus. For a particular color among the plurality of colors, wherein the storage unit image formation according to claim 6, wherein storing the position deviation amount of the toner image of a color other than the specific color for the specific color toner image as the predetermined amount of the resist apparatus. And Turkey controller to output the image signal, Latent before the effective image areas of the latent image bearing member by that reciprocally scans along the modulation light in a predetermined direction by the deflection mirror surface while modulating the intensity of light based on the image signal output from Kiko controller An engine unit having an exposure unit for writing an image; Using an image forming apparatus including an engine controller that outputs a write request signal for requesting an output of the image signal to the exposure unit before Kiko controller, scannable scanning range along the predetermined direction in the position of the one end portion side, and the at a position outside the scanning range corresponding to the effective image area of the latent image bearing member, the other scannable scanning range along the predetermined direction from the one end portion side a detection step of outputting a detection signal to the engine controller to the outward light is detected by a sensor to be scanned on the end side, the engine controller based on the detection signal from the sensor is a pre Kishokomi request signal output And the forward path data for performing the forward path write and the backward path for performing the backward path write by the backward scan before the write request signal is input to the controller. A data creating step of creating data, in response to an input of the write request signal, return document by backward light scanned from the forward writing and the return path by the outgoing light on the end side of the one image forming method characterized by comprising: a writing step, the performing write.
